Chronograph calibration / precision experiment suggestion.

09 September 2013 - 05:12 PM

I have made an observation that a particular brand of chronograph is calibrated to give higher readings than the majority of others.

 

I propose Punkworks conducts a test to compare chronograph readings between several commonly used chronographs to see how reliable they are.

 

1. Chrono a marker to 300fps

2. Fire the marker across as many chronographs as possible and record the values of each chrono.

3. Calculate the differential to the usual Punkworks Chrono. (baseline value)

 

 

Analysis:

a. Variance of the mean of each chrono compared to the baseline mean.

b. Standard deviation within a chrono's values and variance from the baseline.
