Cycling clarification

I started a round and did 25 days of p2. I decided to try cycling so went to p3 for a week and am back in p2. I'd like to complete 2 weeks in p2 then the 3 weeks of p3 and finally p4. This will be my final round forever. Is this ok or do I have to complete my p2 with 23 days instead of 2 weeks? This part confuses me.

Btw..I had completed 2 full standard (no cycling) rounds previously.

Advice is much appreciated. Thanks.
