Well you have to think that most of the items are feeding material at this point, if I could rank the importance of items at our level right now it'd be Peronamin and Pero Pudding since you get more uses out of it. No matter what you do it seems like those materials are the hardest to gain now and you need them being someone who waits 3-4 hours for a full charge and 30 minutes for a full charge and you only get 4 full Kasumi hits. Sometimes you fall asleep/forget since the two fill up at different times. It's that whole demand thing, at lower levels you get a crap ton of those things, but once you hit 30, you're extremely limited on how you can get them. lol But yeah, I do understand what you're saying. It's more useful to people who don't know that trick, are starting out, or have poor luck since if you do have poor luck you're just happy to get a SR period. xD

That worked for me once, then the SRs started playing tricks on me. So ultimately I just alternate from the outside cards and make my way to the middle. It also works sometimes but not always. It's like you have to feel the space you're clicking on to figure out where the damn SR is.

Even Gacha tickets are useless now, owning every N and R card except for the event ones. So I feel your pain too. lol
