Actually, knowing the wait time is significantly more important. As i've noted in previous posts, I've never gotten the SR from anything less than 2hr30min. It is possible to get 2hr30min wait time from a single R Gacha ticket, but that would be (i guess what we could call) a "step-up" for the kurito basket. The vast majority of the time you put 1 R Gacha in you will get a 50min wait time.

Knowing the statistics on the drop rates for each wait-time gives you a target, then if you think you can beat the odds or that it is more efficient to hope for a "step-up" you can evaluate from there.
