Converting a money line into a percentage:

[SlickFazzer]

"Convert a money line into its equivalent win percentage by dividing
the amount you risk by the amount your ticket will be worth if your
bet wins. The ticket amount is your win plus the amount you bet."

"If the money line is negative, then take the money line and divide it
by itself minus 100. For example, a money line of -129 converts to 56.3%:"

= -129/ (-129 - 100)
= -129/-229
= 56.3%

"If the money line is positive, then take 100 and divide it by the money line
plus 100. For example, a money line of +109 is converted to 47.8%:"

= 100/ (109 + 100)
= 100/209
= 47.8%

Correct. But how many here have no grasp of these basic betting
fundamentals?

People would rather be able to handicap a game than do math. The average sports bettor looks down his crooked nose at "math plays". Handicapping is way sexier but perhaps impossible for that vast majority to do successfully.

maybe the reason 95% or more lose long term.
