Not really.

Assuming 5ND was kept instead of changed to 3 days in Jan:

Say you had 54TH mining end of Feb, and turned them off March 1st, ramp down time was around 146 days in Jan, it would have been more in March, but for arguments sake lets keep it the same.

Block was found on 2th May, which is 81 days after you turned off your miners. So by then you would have ramped down by at least 55% or roughly 24TH.

Pool N avg was 7.45PH when the block was found and the block was worth 8.31423879 BTC

So your pool reward percentage would have been 0.024/7.45*100 which equals 0.322147651%

That's 8.31423879 x 0.322147651% or 0.026784125 BTC

BTC price was aprox $9750 so the most you could have lost was pretty much $261

If you would have kept mining the entire time after the switch to 3 days you would have made 0.05356825 or around $522 when the block was found in May

Thanks for the great write-up.   The extra 81 days of electricity would have been significantly more than $522.   Just a matter of how much I wanted to loose I guess.  The halving hurt as much 5->3nd
