I presume watts ÷ weight for Zmap makes mine 3.5 and zftp 2.8 so I presume I'm in development cat . I prefer to race in a Cat where I feel competitive rather than just riding round to pick up finish points in a higher level .
Yes you seem to fit in C dev as long as those are your real numbers at the moment.
As regards your comment about finish points, things are VERY different now. It's much more like how SBP was supposed to be (if you remember that).
Every segment has FAL points for EVERY position. So if you have 50 riders in the race. 1st gets 50, last gets 1 and everything in between.
So for 10th place you'd get 41, 40th place would be 11. So wherever you are you have something to play for.
FTS is almost worthless now. So the days of people rolling round the back smashing the sprints are gone.
(10,8,6,4,2 points for the top 5)
FIN points are the same as FAL points but you get them at the finish. So it's worth trying to outsprint your group.
