You don't have to memorize 100s of tables. That is completely unnecessary. The textbooks that I use present a series of tables in sequential order. Trust me, I haven't learned any polysynthetic languages, but I've never had to memorize 100s of tables. I basically adapted the Dowling method
https://www.rci.rutgers.edu/~wcd/Latin.htm for other heavily inflected languages besides Latin.
Trust me haha, you really don't need to memorize 100s of tables for a single language. I've been heavily influenced by Dr. Alexander Arguelles, probably the greatest polyglot of all time, who uses primarily the assimil and linguaphone methods of learning language. These methods involve gradual assimilation of vocabulary and grammar. But memorizing declensions and conjugations is indespendible as a foundation, and increasing confidence in your reading/speaking/writing skills.
100-200 tables of a single form, sure. But 100s of tables of seperate forms no. I believe that I misread your post at first.
100-200 tables of a particular form is actually very easy and not that time consuming.
