could you please help me with the following problem.
i am trying to calculate an adjusted expected ROI of a tipster.
so lets say this tipster has 10% ROI but you cannot reach this as odds are sometimes worse then advised.
example:
lets say a tipster advised to bet on team x with odds 2.38 but you cannot place your bet at this price, instead you can place it at 2.26.
can you just calculate it like this?
(2.26-2.38)/(2.38-1)= -8.7%
or do i need to calculate the difference between the implied winning chance?
or none of the above?
thanks for helping a rookie
