Not true Eddy, the numbers in the programme corresponded exactly with what you were observing throughout a race with the exception of the alterations, which WERE manageable, but which became too prolific due to bad race management.
The management started to give in too easily to riders who felt they deserved to be moved up the order.
I've said it before, but I arrived at the TT in 1984 having won the Senior Manx in '83, and was given No. 73 for the Senior, and No. 80 for the Premier Classic (unlimited race).
I never complained (though I was a little cheesed off), and went on to finish 9th and 7th respectively.
And before you start, the bikes were pretty quick (RG500), admittedly not as fast as today's bikes, BUT, there were nearly 100 starters, thus lots more traffic for everyone.
And if you look at the quality of the field, there were good riders finishing right down to 20th place.
So tell me why it wasn't a problem in 1984, and it is now? Everyone's got fast bikes now, so it should be less of a problem.
