Excludes those at the lower end of the field a bit!
OK if you are in the top half, slightly undermines the "you against the clock" attitude that a lot of newcomers enjoy.
Not at all.if you manage +112% or +128% it's still a direct comparison with the winning time and those you like to compare with, your own peer group. So you would know on the day, say you are at 118% and your peer is at 116% he/she was a little bit better on that day than you were. Comparing times over a fixed distance course on different days and inevitably in different weather has zero value as a guide to where anyone is, you have to essentially confront it's position that matters, and so long as you see improvement as getting higher finishing ranking the comparison with either winners or peer group is valid.
The old fixed distance and purely time cased system has so many flaws it's a complete nonsense.
Just for interest, the CTT calculate (under their antiquated system) a "best all rounder" at distance (for men) of 50, 100 miles and 12 hours TTs. They simply take the best average speed at any one qualifying event and convert it into an mph average. OK so far? Then the silly stuff starts - the AVERAGE SPEED over all three distances is the average of the averages...how does that work?
Lets say - 50 miles in 100 mins = 30mph
100 miles in 230 minutes = 26.1 mph
12 hours, 280 miles = 23.3mph
Under CTT BBAR rules, that's an average of 26.46mph.
Doing the time/distance calculation properly, the average spped over the entire distance is 24.57mph
A bit different, and seems to make the riders look faster on average than they actually are - most odd!
I knew all that maths study would come in handy sometime...
