when you average the number on a daily basis it gets you somewhere indeed, however mostly at least in the past 8 years I've preferred live betting sessions. at the same time, most of the matches are scheduled during the weekend, therefore Friday-Sunday runs. probably my longest betting session during a weekend was close to around 30 hours. so getting back to the 12-15 average / day, that's totally offset as I've had loads of weekends with hundreds of bets placed, even some with thousands.
could not provide a precise winning % even if I wanted to. about 300k predictions I have stored and tracked, and for those the win rate would be in the 60%+, without taking in consideration correct score predictions as those are close to impossible, more like luck bets.
the odds I usually like playing are within the 1.80-2.20 range but it depends on multiple variables as I described in my previous reply on the post. I won't disconsider an event that has a say 1.40 odd, however will get quite mad losing on that.

overall the mindset is "play to win" not "play the odd" or "play Messi" or "play Chelsea" etc.
between pre-match & live betting I will always go for live betting. there's no level of comparison from multiple points of view, but it also depends a lot on the bookmaker/platform.
