Ask me anything in the comments, scroll down in this description to see further tips. I will put more info here if it’s needed.
Estates: Keep crownland over 20% to avoid negative ticking autonomy. As you get more land, try to give out one “useless” monopoly to each estate, that is a monopoly that is a bad trade good. Give supremacy over the crown to nobility and +10 loyalty/influence to Burghers and Clergy. Always keep seizing land at 50% estate loyalty, and start to grant the +1 dip/military as long as the crownland doesn’t go below 20%. If you keep this up, you will have over 75% crownland close to the year 1600, and you should now revoke all privileges except the supremacy over the crown and the +1 monthly manas. Once absolutism hits, you are now in the best spot to get 100 absolutism fast.
