This week, 0.625 units profit on 3.126 staked, so +20% ROI.
I like to only really look at ROI based on the entire season and if possible over multiple seasons though. In the short term, everything can happen and I would argue that even a season isn't long enough given the limited average edge. I would sign any year for +3% ROI and not too high swings right now honestly. I only ended 3 out of 8 previous seasons above that. I do need to get my stakes up though as I have been way too conservative, at the same time I can't say confidence is sky high so keeping up the streak being unbeaten over the course of the season now since I started betting is one of the things that keeps me busy. The grind is real :)
