I initially changed this to 40, as the specification we have says BPR between 30 and 39. The problem is that this leaves a gap between 40 and 59 which is undefined. Builds 60 and up are special and should never be considered for hgupdate-sync, but after contemplating this, I agree with the original author's conclusion that the best way to deal with 40-59 is to assume they are also BPRs. In reality, I don't think we have any release with builds in that range, so it doesn't actually matter.
