In the case of Chain Lightning, no.

Chain Lightning now stuns. If you can hit the monster with at least one out of the four hits, you can stun the monster, given the 90% stun rate. This will at least disable the monster until you can hit again. If you had a single-hit skill that had a stun rate, you'd miss and have the monster barge at you at top speed.

Why would you train on a monster you miss anyway..granted you might do that but it's sorta dumb to do. Even a 10% miss rate. (thought it seems the acc formula was changed in Chaos so meh..)Anyway, training on a monster you miss in the first place isn't a wise idea. Sure maybe you can see LHC as an exception due to party help but it still won't matter. Multi hit or single hit if you can't hit the monster and someone else can, no matter the outcome of the hits you're not going to beat someone who hits 100% of the time. Even training on a 5% miss rate theres no promise that all 4 hits are going to actually hit.
