I'm not a fan, mainly cause my PR's are wrong and it isn't intuitive how to update them. It might just be due to my web browser from 1997 at work, so I'm not casting final judgment till I get home.
I would have preferred that they leave the user interface alone and just get better at accuracy/speed of posting results.
I would get annoyed when I'd put a race on my calendar, even update the 'unofficial' time after the race, submit the results link, and then when they upload the results for it, it drops off my page and I have to go search for it to claim it. Isn't the point of putting it on your calendar, submitting your unofficial time + results link, etc., so you wouldn't have to go search for your result later?
The new layout is kind of meh, I just don't like how you're kind of scrolling forever to see all the results. I haven't even raced THAT many times (I have 27 on my page) and it feels like a lot of scrolling to see them all.
