Accumulation and intensification query

Dear T-mggers,
Merry Xmas! I noticed in CP’s book The Poliquin Principles he prescribes intensification and accumulation in the same workout as a advanced program for bodybuilders. Now assuming one follows such a protocol would you say just do 5x5 for 20-30 minutes with 180 rest between sets and then a accumulation program for the rest of your workout time then 3-4 weeks later do say 6 x 2-4 then change it again infinitum.
Is this enough variation instead of 3-4 weeks of 5 x 5 then say 10 x 10 then back to intensification?
Sincerely Thanks
