Lets see who spends the least to get the best bike split - and who spends the most! and there is no shame associated with the big spender/slow rider catagory - be proud! The number from the formula below is arbitrary and means nothing, but allows us to compare with each other.
e.g
USD$3000.00 Bike (include accessories such as power, aero helmets, disc etc in your cost)
5:55 IM bike split
Result = minutes x (USD$ bike cost/1000)
355 mins x 3.0 = 1065
The lower your result, the better.
