I think a couple things might be happening -
- early E setups were lacking for speed, but they appealed to many in calm/moderate conditions because of the very slow pace they were capable of, and some are trying to do this today, even when it is windy and they would be better served going faster.
- some flying E have simply not "updated" their setups to go faster.
- some benefit from the slower flight speed (more time to think), and it is simply a tradeoff of getting beat up a bit on windy days for an advantage on less windy days (hopefully the majority for those in this camp).

Matt just might have a ride or two on a modern competitive electric soon enough!
