You should have to complete the ride distance you intended when you set off. If not, then we might as well allow people to start a 300, bail out after 200 and still claim two points.
that is a commonly held opinion which could happen if it was voted on at the AGM or at Commitee level (currently there is no such requirement). It would either require a lot more input from the organiser and also FF to flag a rider on a calendar event as "ECE pending" or something like that before both parts were submitted but as ECE's are perms they do not need to be submitted until 14 days after the ride. I don't think organisers and validators would relish the thought of sitting on their finish list for this length of time (having just gone paperless with event validation so it can literally all be done and dusted the evening of the event or the next day). It's also completely going away from the original ECE benefits but if we want it for the sake of virtuousness and purity so be it.
An alternative is the idea of having to go back and scrub a previously validated ride; this is both messy and labour / email intensive; possibly between the rider and the organiser (who may well not even know what an ECE is)
Either way I can't even ask for a volunteer "ECE Mossad" to help me in this task as although I have start lists of pending ECE's they don't say when the calendar event was supposed to have been ridden as these details all currently only exist in emails to me and the rider or presumably in the AUK server somewhere (which creates some problems of its own now if peeps send tracks in without reference to what they are for as many riders have multiple ECE's of different configuration open at a time) so it requires a lot more work than I'm willing to put in. So I hope someone else is willing to take ECE's over.
I'm not poised with toys at pram edge just saying ECE's are a huge workload now even with FF's recent excellent entry system and I don't have time for any more checking. In fact we may arrive at regional ECE delegates at some point in the future although that's a lot of work as each would have to have their own suite of ECEs much like the DIYs are now.
It could be done if it was wanted but I think all it would do is reduce the number of ECE's especially if the calendar event was worth distance / RRTY points.
Now, who wanted to administer EPE's?
