Time to end this, since I stopped because of a lack of time betting before each Friday and sometimes completely missing it, here are the results for each league on its own and the finals for the remaining games

Premier League +1.87
Bundesliga -3.74
Seria A  +1.35
La Liga +4.65
Ligue 1  +3.69

No winning multipliers!

Last matches balance
- Individual bets balance  +7.82
- Multiplier balance -14

Total after all rounds and 327 games

- Individual bets balance +13.44
- Multiplier balance +2.58

Conclusions? You would have earned around $15 for a year, with a bankroll somewhere in the upper $40, wagering $327.
