I think the PL rankings have certainly helped me to me a bit more careful and less rash in making my decisions without doubt.
After seeing myself in 97th place at one point, I was a bit embarrassed, so started to play the focus games properly instead of my usual "having a laugh".
I definitely play a lot better now and that's mostly down to the BPP rankings making me want to get better. The amount of times, I've thrown away AQs, JJ, AJs after I have been re-raised is much more than before. Previously I didn't give a fcuk and would call anyway, as it's only a $1 tourny etc....
It definitely makes you concentrate for sure and thanks to GaF for all his efforts.
