Preliprins stuff is just 1 piece of the whole thing. The Soviets had many charts. Preliprin’s is divided into “zones.” They also had charts for how many lifts per week/month/year/4 year Olympic cycle should be done in each “zone.”
This is a similar chart from a Sheiko PL routine. It shows lifts by zone, per month.
1 chart would be only half the story.
Also the Russian version of the chart says specifically (10) - 90% snatches and ( 7) 90% clean and jerks. So presumably if dude had made a chart for powerlifts, the numbers for 90% lifts would be lower. Maybe around 3, like Louie does for M.E. or Bryant does with Jackson.
