Not 1 person I have mentioned and I know there's more who have ever said you have to have a single digit E.S. to be competive or shoot small, if they have post it here.
Have you ever been to a 1,000 yard match? Shot with some successful 1,000 shooter? or just read about it
If that isn't enough for you Google positive compensation shooting and read the thread on accurate shooter.
The late Stan Taylor talks of a 3.7" group he shot at 1,000 yard match that had an E.S. of 29. Theres lots of examples out there that reasonable double digit E.S will shoot small at 1,000.
Where is anyone here saying you need single-digit ES? Single-digit SD, maybe, but SD is very different from ES. In a Gaussian distribution, SD is approximately 1/6th of ES.
