I use this one for quick checks on power/speed scenarious:

Have you done any Chung method testing? You need a GSC-10 (they're like $30) since GPS isn't accurate enough and Stages may be iffy but I think some on Slowtwich may be getting acceptable results with Stages.
The Rt 29 one was the one on your blog, so I think from June?
Lets get back to aero. I have not done any Chung method testing, but I've often thought about giving it a try. I have two skinsuits I'd like to do it with to see if it makes any difference. My understanding is that basically you try to use the same position and same wattage for set distance on a course to test differences in equipment... or I supose you could use same equipment, same wattage, but alter position to see if one position is more aero. Is there anyr reason why you're specifically listing the GSC-10. I don't use that, I use the Garmin magnetless speed sensor on the hub because I get cadence off my Stages. I'm a long time user of Stages power meters and they definitely had some growing pains early on with the battery door issues etc, but my experience with them has been that they are accurate and reliable enough for my purposes. Am I sure that 100 watts on a Stages is the same as 100 watts on a Quarq or 100 watts on an SRM, no.... but my experience seems to say that 100 watts on the Stages is pretty reliable to 100 watts the next day and the day after etc.. and from bike to bike across 3 diffirent units.
If you want to compare my numbers Non-TT to TT this year on the same course... Last year at Oldman's, I did 19:47, 290 watts, 25.9 mph. This year, 18:19, 324 watts, 27.9 mph. Weather was abviously different. Last year, it rained during warm up, but the course was still damp during race. This year it was flat out downpour. I wouldn't say that either was particularly windy. I was using an 88mm front wheel in both races and felt pretty stable. I was extremely caustious in the corners this year, due to standing water.
