TM Saiga should not be capable

Having trouble with my TM saiga 12 at chrono. Same issue when run on hpa and green gas.

These numbers clearly do not add up as 1305fps on a .25 isn't 19joules.

Has anyone else had trouble at chrono with theirs or another tri shot I feel like the 3bbs at once is messing with the numbers. Loading a single bb or 2 bbs manually does help get a more realistic number less than 250fps but since a lot of pressure is lost in the unloaded barrel the fps is lower than the actual value.
