I get your point, but if you're referring to her damage when you say "the same game that your Sonya has played", I just want to make something clear.
Demolition has the most damaging combos in all variations. As you can see, Sonya can barely get past 40% midscreen, unless she uses leg grab as an ender which means she's FUCKED because reloading her grenades in the neutral game is a challenge. With Kano, he can get +50% damage with 2 bars off his starter 50/50, while Sonya gets mid 30% off B14 and B33212 with three grenades (without a divekick, of course). In other words, Sonya can only surpass the damage that Kano gets with 2 bars by doing an Xray combo. In fact, I shouldn't even use this video as an example because all combos were ended with leg grab which isn't viable in Demolition at all.
