I did the same on my latest review, so not sure if this is partly directed at me. Not offended if it is.
I reviewed one from Feb starting with the line "Back in the heady days of February 2020, we used to do this thing called punting" . That was more of a joke rather than to deflect any criticism for still punting. My last punt, for what it's worth, was 5 March. Even if I wanted to be selfish, I'd have no excuse if my missus found out I was out and about as I wouldn't be able to say my normal "I was at the gym / visiting mum / at the pub etc".
I , like others, often leave it a month before reviewing so as not to be identified by the SP, especially in the case of this latest one being a negative. Don't want my number to end up on Saafe or clienteye in revenge.
