I have changed what i do in last couple of days which may have had an effect, time will tell.
Basically, any non fav, close match i will do £5, any reasonable fav i will do £10 and hot fav £20. May just be coincidental, but the up swing has happened since i started it, as i say, time will tell.
As for variation, it’s normal. For me, it looks like this for 1W at the moment. Without changing anything. I see more and more in the community that people are experimenting and it seems to me premature as if they want a smooth ride to the top, unfortunately it doesn’t work that way. Anyway @paulwilko10, good luck!
