I've nearly finished the current 6-week block. Have missed a few work-outs. Next week is meant to be an easy week to end the block and then FTP test to reassess fitness, and then start another 6-week base block.
If I've only maintained the FTP I had at the last test, that will still be a reasonable result, as it's almost at the peak I had before PBP, and possibly as much as 50W higher than this time last year.
