Basically, if you see a shattered screen or a SS3 *even on a single), you're getting an SSR. As coolconnor stated, it could mean any number of SSRs on a multi. If Goku goes SS or SS2, that means SR, although I believe it is still possible to get an SSR with SS2 (though not guaranteed like SS3).

Rainbow text might mean SR but I could be wrong.

Sometimes you'll get bonuses for doing multi-summons instead of singles (like discounts, having a guaranteed SSR (GSSR), or getting some extra items and such). In most cases, it's better to save for multi summons.
