Half Point Calculator for Parlays

[slope99]

Say I have 3 team parlay.

I use Half Point Calculator separately for each game and it gives me:

1st game edge = 3%
2nd game edge = -1%
3rd game edge = 2%

so total edge (decimal) = 1.03 * 0.99 * 1.02 = 1.04?

I feel like this is wrong.

Going to slink this to the Handicapper Think Tank so the experts can review it with you, slope!

Found my own answer. Each game treated like separate event (parlay odds converted to per game odds). So total Edge equals SUM of three games.

i was right first time. i think lol.

here is an example. 100$ on a parlay, first game 5%ev, 2nd game -2%ev and 3rd game -1%ev.

5%ev means in the long run 100$ will win me 105$.
-2%ev means in the long run 105$ will win me 105*0.98=102.90$
-1%ev means in the long run 102.90$ will win me 102.90*.99 = 101.87$

total edge or parlay %ev = 101.87$/100$ = 1.0187%ev = 1.05*0.98*0.99
