So i am 13 PTs into foolproofing and i am noticing that i am solid with sequencing but i am having a hard time with grouping games, both in out and multiple groups. So i was considering drilling those extensively and then going back to drilling chronologically. I was wondering if anyone would be so kind as to make a list of specifically fundamental in out and grouping games that they found to help them nail down the methodology and send it my way. Thanks in advance
