I would suggest you reconsider doing that.
patter rotation? can you elaborate on that?
there are different approaches you can take for when to advance to the next stage.
either you milk everything you can from a stage before advancing, so it might look like this:
Example
Stage 1: 4 cycles
Stage 2: 2 cycles
Stage 3: 3 cycles
Stage 4: stay, unless you want to repeat from stage 1
or use the stages for a period of time over and over again until you get no recon from stage 1-3. then stay on stage 4.
Example
Stage 1: 1 cycle
Stage 2: 1 cycle
Stage 3: 1 cycle
Stage 4: 1 cycle, repeat again to stage 1 unless you are satisfied with & get no recon anymore from the previous stages
