I agree, it may be highly offensive to clients. Why are you doing it?

Personally I'd configure squid with only individual pools. And limit
each user IP separately.

ie:
   delay_parameters 2 -1/-1 32000/64000

Why not add here:
   delay_access 2 deny bpool-1
> delay_access 2 allow all

... which means you can get rid of the unlimited pool above.
bpool-1 people will be left without a pool at all, and get through
without speed limits.

That said, there does seem to be a problem. Delay pools should not go
negative at any point. Is it only happening on POST?
