To someone doing about 280w in a TT, like me, finding 15w by comparing a video of me on a trainer to a video of a similar sized/flexibility rider could be awesome.
I say all that golf stuff to say emulation by having a video or pics of known body dimension folks can get a "nobody" like myself probably pretty close on the bike pretty quick with a really low budget.
I've no idea the % of riders who try video. I've posted once here, and need to again since I made changes based on feedback here. If I do, I promise to use a nicer camera.
It would be nearly impossible to to say, x will get you y. You can take two people who are the same height/weight/flexibility and put them in the same position and 9 times out 10 they will have a different CdA. This is why a helmet, kit, socks and even hydration location will vary from one person to the next. Yes there are some "best practices" but in general one never knows unless they take time to either field test, or spend the money and time to go to the wind tunnel.
Time trial positions are also different than tri positions in that TT riders generally don't have to consider hydration solutions and are general at or well above 40kph. At that speed yaw angles are generally quite low <5. If you run a BTA, a high hands position may or may not work due to drag created by the bottle. There are lots of considerations involved and no single solution for all athletes.
