Claims for AAA awards should be made to aaa@audax.uk. It's possible that whilst the role was vacant some emails ended up in the spam folder and were purged before I could get to them so please resend it if you haven't had a response. However, I need to get the 2018 results finalised for the next Arrivée this week and will move onto updating interim 2019 RoHs after that, haven't actually made any visible changes yet, so that's all I've been telling claimants so far.
Similarly, on the subject of spam, if you think you are missing AAA points for DIY rides from the beginning of season (say before Jan) drop me a line, but note that I don't generally respond to AAA DIY track submissions, I just add the climbing on once it's been validated by the PermSec, so there can be a several week delay before any AAA points appear.
I would generally recommend a fixed 50-100m extra climbing margin to be safe, but that depends on what you are using to plan the ride - 10% is a lot once you go over 200km.
