I think it's a automated testing tool that is used, rather than incidents in the beta program. It's used in TV/games production to measure contrast changes and 'score' the result for problems or susceptibility.
Also, saying 'I don't have epilepsy, so why bother' is missing the point of the guideline, in that it was introduced after video games caused seizures in people who didn't previously show any symptom.
PS Not saying I agree with the use of this 'filter' but just trying to help with actual info.

Luther reports the game caused "wide-scale epilepsy failures when tested". This suggests a high incidence of photosensitive epilepsy (PSE) was encoutered amongst game beta-testers. In contrast, the incidence of PSE across Great Britain has been reported to be about 1.1 per 100,000 persons (0.0011%) [Quirk et.al. 1995].
!C's decision to impliment an "epilepsy filter" is presumably based upon Luther's anecdotal observations, rather than the scientific evidence. The low incidence of PSE in the community does not seem to justify such a decision.
