Why does the timing accuracy vary?

Time Servers and Frequency Standards: Frequently Asked Quest...
CDMA basestation transmissions must be synchronous with UTC to within 10 microseconds, typically much better - less than 1 microsecond. This variation is due to the possibility that a basestation might have a GPS outage, a rare occurrence. Under these conditions the basestation must stay within 10 microseconds of UTC for as long as 24 hours. This ensures the smooth operation of the CDMA telecommunications system.

What is the timing accuracy of the mechanical mechanism?

FAQ
The accuracy of the mechanical timer varies with the gear train construction and the condition of the timer. Typically, a factory-fresh 1-hour timer will run down between 1 hour + 1 minute and 1 hour + 9 minutes; a 24-hour timer will run down between 24 hours + 27 minutes and 25 hours + 44 minutes. Periodic maintenance, cleaning, and adjustment are absolutely essential to maintain timer accuracy.

What is the timing accuracy of the electronic mechanism?

FAQ
Duncan electronic mechanism timing accuracy is controlled by a quartz crystal oscillator. The accuracy of the crystal is +/- 0.005% (50 parts per million). The crystal operates at 32.768 khz +/- 1.6 hz. This is equivalent to approximately 4.5 seconds per 24 hours. Actual timing accuracy measurements taken over periods of 24 hours and over periods of 1 week in comparison with the National Bureau of Standards Atomic Clock have shown that the Eagle time error never exceeds 10 seconds over 24 hours.

Why does my gas bill vary?

Frequently Asked Questions
Seasonal weather conditions have the most impact on the amount of natural gas you use. When it's cold outside, your furnace goes on more frequently and runs longer to warm your home. Your water heater also stays on longer to heat the colder incoming water. Aside from weather-related and other changes in your gas appliance usage patterns, your bill may vary due to changes in wholesale natural gas prices, which change based on market conditions.

How much does heat distribution vary?

Skutt Kilns Frequently Asked Questions
A one-cone difference is common from top to bottom of an unvented kiln. You can observe this difference with cone groups set at different levels. The difference can grow great with larger electric kilns, especially when firing to low temperatures. For example, cone 03 has bent on a top shelf when only cone 05 has bent on a bottom shelf. Tests have shown a 30° difference top to bottom on high fires and 80° difference when low firing.

My timing results vary from run to run. Which numbers do I report?

Java SciMark 2.0 (FAQ)
Because of background threads in Java environments, it is not unusual to see a +/- 5% variation in timing results. While this does not dramatically change the overall conclusions, keep this in mind when trying to split hairs. Typically, you should report the highest SciMark number, unless the performance is varying wildly --- this suggests you may have background processes interfering.

How does the timing work?

The Racing System -- FAQ - Frequently Asked Questions
In all the races we've done with The Racing System, we've never used an external timing source. We've never found it necessary. Instead, we use the computer clock for all timing and coordinate with any external source by manual methods. Quite accurate synchronization can be achieved this way and with enough precision to satisfy any normal requirements. We have also found that less complexity means less that can go wrong on race day. We use digital watches for our timekeeping.

Why does sweetness vary from year to year?

Frequently Asked Questions
Sap sweetness has been observed to be lower in years following a growing season when conditions were unfavorable for production of sugar through photosynthesis. For example, if a stand is attacked one year by insects that defoliate the maple trees, the next year’s sap would be expected to be low in sugar. Some scientists have speculated that a vigorously growing tree might use up so much of the sugar produced by the leaves that it would have a lower sugar content the following year.

Why does my through-put vary so much?

FAQs
The tests are affected by "Internet congestion", which could be occuring anywhere between your ISP's Point-of-presence and the computer that servers the test pages. Your through-put readings may be more stable if you try the tests at an off-peak time, such as late at night. You could also try the mirror site which is based in Ohio.

Can I increase the timestamp resolution and timing accuracy to 1 millisecond?

Docklight - FAQ
No, Docklights timing accuracy is limited and clearly not within 1 milliseconds. It further depends very much on your PC's hardware and software characteristics (serial hardware used, operating system, overall PC performance). Docklight is designed as an easy-to-use, general purpose tool for almost any COM port hardware and Windows version, so we cannot make any claims about specific accuracy here.

Why does the EpiCor price vary so much?

Frequently asked questions regarding Biosyntrx products
Unfortunately, a discount marketer has purchased some EpiCor and is selling it far under market price. The contents of the inexpensive product looks nothing like the real thing. These products are, most likely, cut with fillers, which is most unfortunate because pure EpiCor is an exceptional immune system modulator.

What does Timing Control mean?

PERFORMANCE MOTOR RESEARCH::
The MAP-ECU2 has eight (8) timing channels that are used to intercept and alter the signals normally going from the OEM ECU to the ignitor(s). You can advance or retard timing by 30 degrees using a 20 x 19 (380 zone) table. No, MAP-ECU2 is a piggy-back ECU that allows you to modify many parameters but retain the drivability of the OEM ECU. For example, your OEM ECU still fires the fuel injectors so if you install larger injectors, they need to be the same type.

My accuracy is not satisfactory. Why?

Defensio · FAQ - Frequently Asked Questions
If you have recently installed Defensio, then try to be patient. The filter's learning algorithms take some time (usually no more than a couple weeks) to become very effective, so in the early days of installing the filter performance might not be what you'd hope for. Alternatively, if your blog receives a low amount of spam (say less than 100 comments per week) Defensio will have a smaller sample set to draw from, and may not perform to expected levels.

How does viscosity affect the accuracy of the FMI pump?

Fluid Metering Frequently Asked Questions
A.The FMI pump is positive displacement and, in general, viscosity independent. However, viscous fluids should use lower RPM drives (400 RPM or less) with pump heads adjusted to longer piston strokes. There is no absolute value for the maximum viscosity an FMI pump can handle. For extremely viscous fluids, pressure feeding on the inlet side of the pump and/or heating of fluid are commonly used to aid in feeding fluid to the pump.

Why does the yogurt texture or consistency vary during the year?

Welcome to Redwood Hill Farm
Since we use the milk naturally as it comes from the goat, there is a seasonal variation in the milk solids which causes the texture to vary. The goats seem to know that in the winter we need more solids which causes the consistency to be thicker and in the summer less which results in a lighter, thinner texture.

Why does my blood pressure vary so much when I monitor it?

Columbia Behavioral Cardiovascular Health & Hypertension...
Everyone who starts to use a home monitor is surprised by the amount that the readings vary from each other. Even if you take three readings in a row (as we recommend) they may vary by as much as 20 points. Typically, the first of the three will be higher than the other two. Blood pressure goes up and down as we breathe in and out, so no two readings are ever the same.
