Bullet Seed is a Physical attack, so Light Screen doesn't affect the damage, and I guess the Bullet Seed combo would cost (12+16)*2=56 energy if used on A1 because of the consecutive energy penalty or (8+12)*2=40 energy if used on A2. The BAP would probably just be 20*2.25=45 in Cinccino's case, factoring in Technician and Skill Link.
10 [Surf] + 3 [Rain] + (5-2)*1.5 [STAT] - 5 [Light Screen] = 12.5~13 and fine if you really want me to post my calcs I will, but reffing posts will take a little longer.
