Help needed, math guys

This topic should be in Handicapping Zone, but I might get more attention here in this case.

I have probably made a mistake again and have posted false info in two topics.

After I started to make tracking program in Excel for my bets I saw there might be a mistake.

Math is so damn tricky as is betting also. If you look thigs differently, you will get different results and usually a first one is likely wrong. Which is correct way to calculate break even prices for parlays. To solve bookmakers vig on whole bet, as I first did, or just a break even price for line you are betting? I think a correct answer is a break even price line you are betting, but I'm not sure.

Here are break even prices for a line you are betting on and if you can't beat these odds on single wager you can't make profit on parlays in a long run.

Odd offered: -105

2 team parlay -111 (break even 52.61%)
3 team parlay -117 (53.92%)
4 team parlay -124 (55.36%)
5 team parlay -131 (56.71%)
6 team parlay -139 (58.16%)

Odd offered: -110

2 team parlay -122 (break even 54.96%)
3 team parlay -135 (57.44%)
4 team parlay -151 (60.16%)
5 team parlay -171 (63.10%)
6 team parlay -195 (66.10%)


And this is what I posted earlier (modified a little bit)

**********


True odds on single wager with a 10 cent line and the original odd was -105 and the vig 2.4%.

5 team parlay -137 (57.81%, 11.44%)
6 team parlay -145 (59.18%, 13.56%)
