How would I equate this prop???

[Bluehorseshoe]

If a book is giving the "Will there be a score in the first 7 min. and 30 sec. of a football game" and Yes is -240/ No+190, how do I figure what out what their price would be if it was adjusted to the first 6 min and 30 seconds of the game?

To do it accurately is quite difficult.

Very poorly done, you could just utilize the fact that you are losing 1 minute off of 7.5, and adjust accordingly. But since the likelihood of scoring is not equal in the first minute as it is between the 6 and 7 minute mark, this would likely be useless. To actually create a value, you would need to chart all scoring plays in the first quarter of games, determine the differences between the 6.5 and 7.5 minute mark, and then adjust the line accordingly.
