Been diving into the D'Alembert system myself, so I appreciate the discussion here. I’ve tested it on NBA bets for a couple of weeks, focusing on games with tight spreads, like Bucks vs. Heat or Warriors vs. Nuggets. The system’s appeal is its gradual approach—adding a unit after a loss and pulling back after a win keeps the bankroll from taking massive hits, unlike some aggressive chasing strategies. In basketball, though, the high variance can mess with it. Blowouts, like you mentioned, or games swinging on a single overtime can throw off the rhythm. For example, I had a streak betting on underdogs with +4 to +6 spreads, and while D'Alembert kept losses manageable, the wins didn’t always recover the deficit fast enough due to the juice on NBA odds (usually -110 or worse).
What I’ve noticed is it works best when you’re selective—stick to games with balanced matchups and avoid betting on teams prone to inconsistent performances (looking at you, Clippers). Data-wise, I tracked 20 bets last month: 11 wins, 9 losses, and ended slightly down (-1.2 units) after fees. The system’s strength is it limits emotional overbetting, but the downside is the slow grind, especially in a sport where momentum shifts are brutal. I’m curious about your approach—do you adjust your base unit based on the odds or game type (e.g., regular season vs. playoffs)? I’m leaning toward tweaking it for lower-variance bets, like totals, but haven’t crunched enough numbers yet. Anyone got insights on adapting it for specific markets? Still on the fence about making it my go-to.
