Im surprised no one has responded yet but heres the typical responses youre going to get...
- lolsamplesize
- only worry about the green line
The reason you shouldnt care about the redline is because its natural for it to be negative because every orbit you have to post a bb and sb. This is the same reason why our winrate positionally is going to be worse in the blinds then other positions and most time negative.
Just think about the % of hands youre going to play in the bb/sb. Say you play like 10% of hands that means if the btn or someone else would raise every time you'd lose 90% of your bb/sbs.
Imo its probably more of a leak to have a positive redline over a decent hand sample than it is to have a BE or negative redline.
Hope this kind of helps
