Repitching yeast

[AnacortesBrewer]

Brewed a RIS today and didn't have time for a starter. Will it be ok to pitch another smack pack tomorrow to help make up for under pitching?

That's obviously not ideal, but better than pitching just one pack. To be honest if this is a 5 gal batch of an RIS with an OG over 1.080 I'd think seriously about pitching 2 packs (so 3 total).
