There's some knobs that can be adjusted. Presumably they're some kind of tolerances for things like weight, hr, cadence, drop-outs, etc. In theory as long as your weight is consistent across the league, weight shouldn't cause a ride to need manual approval.
When we get to league #3, I'll probably spend some time trying to figure out if/how any of those knobs ought to be turned, particularly for things like drop-outs and cadence/hr as folks don't always have a cadence or hr sensor set-up.
In the mean time, don't stress on manual approvals. They only take a couple seconds once I'm on the website.
Enjoy the rides. I certainly did up until last night when my legs gave out. One of the advantages of setting a slow pace is I can focus on how bkool rendered the ride and how it compares to real life, which was fun/interesting. I was particularly curious to see what it'd do with the desert landscape for Sand Flats Road. It's actually a pretty climb in real life, but bkool loses 99.9% of the texture of the various petrified sand dunes in that area and all the red-rock colors making it a bit boring. Given I'll never ride it again in real life a ride in the virtual world seemed appropriate (we take shuttles up to the start of Porcupine there these days, which saves the legs for the brutal downhill & a second ride later in the day)
