[QUOTE=bkeiller;23251]Just curious how much a 1/2 run is worth on a baseball total. Im sure it is worth more when the total is 7 rather than 9 but is there a common rule of thumb?? Today playing the over I had a choice of 9 1/2 Ov Ev or 9 Ov -125. Thanks.[/QUOTE]
Here's a chart I have used for quite a while, these should be close. Maybe a little conservative, but close.
6.5 to 7--28 cents
7 to 7.5--26 cents
7.5 to 8--17 cents
8 to 8.5--16 cents
8.5 to 9--23 cents
9 to 9.5--22 cents
9.5 to 10--15 cents
10 to 10.5--14 cents
10.5 to 11--21 cents
11 to 11.5--20 cents
11.5 to 12--13 cents
12 to 12.5--12 cents
For example:
the move from 9.5 to 10 is 15 cents, so over 9.5 -115 is equal to over 10 +100, conversely, under 10 -115 is the same as under 9.5 +100
