yep, keep some speedloaders in common weights on hand incase you have reason to doubt a players claim, and make sure there's a hard backstop to the chrono range so you can hear a reason to doubt a players claim.
then just tape a strip of paper with the fps conversions for each bb weight at the site joule limit on the chrono so you don't have to re-set the weight settings or try to do math on the fly.
yep, guns do fucky things when the hop is all the way on or all the way off, best to set with the setting you're gonna use in game.
the other issue with .2's is ofc the gats that will legimitately come up kosher only for them to be spicy when the player puts their game weight in. no malice required only ignorance.
my other favourite is not bothering to chrono pistols, unless they're co2, because it's simply not possible to drop a longer barrel in.......
