>>18601884with both defense and special defense at +6 stored power only does 16 - 18.9% to heatran
unboosted charge beam only does 6.2%-7.5% and there is no guaranteed boost
the damage calcs for flash cannon are as followed
42.6 - 50.7%
28.9 - 34%
21.3 - 25.8%
17.2 - 21.3%
14.2 - 17.2%
12.6 - 15.2%
11.1 - 13.7%
these damage calcs are assuming its 252hp/252+spd which most ppl don't run because no physical bulk, the typical spread is usually 252/88+/166 so the flash cannon damage will probably do even more
it's gonna take 6 turns to get to +6 special def actually more than because of softboiled recovery so 8-10 and even at +6 its still does nothing to heatran so it will take a few charge beams before it can do any damage, it wont do 30% till +2 which will take at 2-4 more turns to get
by then heatran will have gotten a crit and KO'd
