Given that the chrono will not be spot on and neither would the scales you are always going to have a variance anyway.
I don't think anyone, FT or HFT would try to cheat the chrono. Peer pressure would soon stop it because that person would become "known".
Will be interesting to see how these pellets perform. If they can get the weight tolerance tight then they can start work on the size
Does raise the option of BFTA getting a sleeve of the high tolerance ones and use them on the chrono? Maybe an Exact and an Express version. Then everyone gets tested with a standard pellet.
For my own rigs I aim (!) to set Exacts to 777 and Express to 805. I am also going to have to shell out on these fancy ones to compare as I guess many others will do.
I just checked a tin (the other day) of Express and whilst the majority (54%) were 0.510g there were around 37% in the .505 and .515 tins and a small number came out as .500 and .520. This on scales with 0.005g resolution.
