odds table info

i had this before but cant find it now ....it is a table that shows what the odds range(betfair odds) should be when a certain event occurs during a football match. eg what the odds would/should roughly be if a goal is scored by away team whos prematch odds were 1.76 or what the odds would be if home team with odds prematch odds of 3.65 took lead after 49mins etc etc

help to locate this would be greatly appreciated...thanks
