1990 Topps sequences

I know Topps' collation was extremely predictable in 1990 (for instance, you can predict a Frank Thomas card from 5-6 cards out) but I'm curious how reliable they are in other years.
I remember someone referring to themselves as Code Breakers selling the sequence to the "big" cards in 1987 Topps way back in the day but the sequences were very large (40+ cards) and were repeatable.
I've noticed sequences in 1991 Topps but with less certainty than 1990 Topps.
Does anyone else know how predictable other Topps' years are?
