I came across an airgun pellet that specifies the ICAO G1 table
https://www.schulzdiabolo.cz/en/pellets/premium/77-match-premium-light.html

i then found this source of drag tables that has what appears to be ICAO G1 table (plus more)
https://jbmballistics.com/ballistics/downloads/downloads.shtml

the format of these tables is quite a bit different than drag tables in this package (which appear to be McCoy tables)

I want to contribute these tables but i'm not sure how. any ideas?
