I got 4 batches of pellet
I shoot, record fps. look at groups?
what do it do next?
go through all your permutations with each pellet Mr wizzard .
eg ...sized /not sized.
......then stripper 1on /off
......barrel clean /leaded
air temp readings might be interesting and relevant or not
gun temp reading ...the same... etc etc
air cylinder pressures for each test ....
reg pressure at time of test .....
it goes on but think of all the variables and try the ones you think are important before changing to the next pellet .
try to fill to same level at the start of each cycle
a shot counter might help you recognise a pattern or trend....
oh yeah try to "sunlight proof " your chronos ........it would be a shame to do all that work only to find that the readings are out of whack because the light changed at some point.
