I had an idea this morning and knocked up a quick demo.
My first thought was ... very pretty but what's the point?
My second thought was ... hang on a minute, I think I might have a little commission for someone with a bit of software wizardry and more time on his/her hands than is good for them. If you could extend that to have a Randonneur Round the Year adjudicator I would be thoroughly impressed. It would have to interrogate each year's results pages by MemNo, identify which rides qualify for the RRTY (non-zero in the points column) and spot 12 such occurrences in any consecutive months. It gets more complicated when you take into consideration that multiple RRTY runs may occur simultaneously, not necesarrily starting in the same month. No ride can be counted more than once.
Not only would I find such a webtool useful (as RRTY adjudicator), but I would imagine others could use it to check where they stand in the RRTY stakes before they make their claim.
And if you can pull that one off, I'm sure Steve Snook would be along with a similar request.
