I dont know if there is any secrets at this point. remember, there is no advantage in pulling multi vs singles. when I started it out, my initial roll was no SP on the first 10 pull, then Vegeta on the 2nd, then Pika and pan on the 3rd.This quote is hidden because you are ignoring this member.

I have read that since you get daily discount summons for 20 stones. Someone worked out that you have a 18% chance of pulling Broly if you pull singles up to the end of the banner.
if your rerolling, go for Broly first, one you have him, then try to get SP vegeta or SP SB Goku.
