Macguru, the banter on this site is all good fun, and of course what you have suggested although not legal in competition would be a great training device particularly for the coaches of international teams. This has been done before and I daresay it is going on in secret. I was not kidding by suggesting measurement of the elevation shear. Correct.
We could take this a few steps further, like combining it with piggybacked electronic targets to add a bullet speed calculations at the target. Couple this with muzzle velocity and you can have a complete analysis tool for weather, rifle, components and shooter technique; and a data bank source for future retrieval.
Install this gear on the major ranges and people could tap into it with simulation software like Peter Smiths to build their skills and not be disadvantaged by local knowledge.
Have it on a big screen at major events and spectators could see a competitor see the wind change or miss it. Particularly if digital cameras were displaying flags and the target for impact. The possibilities are in fact achievable and could add a new dimension to progressing shooting as a sport. But I certainly would not allow shooters on the mound access to the information. The market for kids who play computer games is huge, and it could be a way of drawing them towards the sport. Its taken a while for a few old boys to use electronic targets, but they are keen to use them when they can no longer pull them.

. Sometimes its hard to get people on the bike, let alone press the pedals.
If you have a copy of Rifle Accuracy Facts, Harold Vaughan talks about Walter Watt’s electronic vane devices (vanes attached to potentiometers) where he linked three of them in parallel to an indicator mounted on his bench. That was in 1960.
