Personally I didn't bother doing this at all, by the time that idea was pointed out to me I was already done with exploration. Looking back on it, I'm not sure I'd of had the patience for it. If you think you can handle that snails pace of progression, go all in with it, like I mentioned there's no reason to rush the exploration stages.
Oh yeah I forgot about that...I've had all the Gacha girls at 100 for so long now
