Thats some strong contest play, especially to formulate that many winners with no crossover plays. VERY difficult to go 8 or 9 of 10 in the NFL on multiple weeks. Kudos, whatever you are doing is working. Of course, two of my strongest contest plays are your two losers....lol.
Out of all of the games you've selected, you've mostly been able to avoid negative randomness (except for Tennessee) that's been very hard to accomplish this season so far. In the 20 games you selected you are +14 in Turnover margin, being a + in the TO battle in all 4 quadrants. You are also +18 points in Defensive/Special teams points. If you continue to win the TO battle in your games by an average of .7 TO's per game and create around +1 ppg in random scoring, you are going to have an exceptional season.
From all the information you relayed you seem like a very strong contest capper so I'm not surprised by your results. Best wishes.
