If they gave Oscars for devices, your would win the best value category for sure !

Not to you specifically, you know all this, but IMO, if you follow a strict protocol in specific conditions (route and weather) you can get very accurate numbers with nothing but a powermeter and speed sensor

To get good numbers, with just a powermeter you require some form of out and back, or loops. Ideally no braking, but some braking can be edited out. Weather requires low, constant wind or no wind. No traffic is preferable. Sometimes “things”, like passing cars, wind gusts and others can give results that need to be removed at analysis. It’s not hard but it’s not click and go.

I believe it's the sum of these "conditions" that make it difficult for many many users.

I believe your app makes things much easier.

With Aerolab and the Chung method when all the data is good, things are wonderful. When some of the data is bad, one can recognize the bad data, but it requires skill.

IMO aerometers can do a few things

1)They can assist in making it simply “ride and get a number”. How "strict" a protocol is depends on how advanced the technology is.
2)They can help pin point bad data such as wind gusts
3)They can provide good data when otherwise bad data would be there
4)They can collect other data that makes analysis easier (air density, temperature….)
5)They can eliminate or greatly reduce the requirements on a venue. Out and back not required
6)They can provide a snapshot of CDA at any point in the ride
7)Combined with other sensors they can help determine the cause of drag.

The value of an aerometer, IMO, depends how far it gets through list.

If a device does it all, How much is it worth ?
If a device simply collects a little more data, is it worth $1000 ?
If a device makes it “press a button”, how much is that worth ?
If a device just picks up wind, but is not accurate, at least I knew there was wind. How much is that worth ?

If a device imposes a whole set of conditions for getting results, is it any better than Chung testing for free ?


My hope if we get to 5, 6 and 7. I know it can be done. That's where I put my money (Literally).
