How long does it take your Powertap to "fall" from whatever wattage you are putting out to 0 after you stop pedaling?
What about how long does it take your torque to do the same?
Normally, after I stop pedaling, my Powertap will next read some lower wattage number (5-100W), then 0. Torque will read something low too (5-30) then zero. Although my torque also often just hits zero right away for the next reading.
Here's where I start wondering though: sometimes my torque will read: 50-70 (whatever I'm riding at), then I stop pedaling and I see: low torque number (ie: 5-30), 1 (or 2), then 0. Likewise, my power will sometimes read 1W (or 2 or 3, something very low) before returning to zero.
Does the fact that my torque/power sometimes settle on 1 or 2 before hitting zero mean that my torque was drifting? Is this normal and should just be expected (nothing to worry about)?
I've checked my torque functioning and all and the auto-zero does work. But the CPU can't auto-zero while you're pedaling and after doing long extended threshold intervals, if the watts/torque are "falling" back to zero but settling at 1W/1 torque right before hitting zero watts/zero torque (ie: an extra second or two of positive W/torque data), does that mean my watts were off for that interval because of torque drift? Anything I can do about this? I always make sure my torque is zeroed at the start of the interval but you can't do anything while you are doing the interval of course...
