Ok. Please note that the delay pools feature available in Squid is
designed for proxies and limiting the Internet bandwidth used, not for
shaping clients. Because of this it only applies on cache misses.

This looks very odd for being an url_regex.. what is it you want this acl
to match?

This pool is equivalent to not assigning a pool to the request, but is
wasting a lot of memory only to keep track of that the clients are not
limited. Why have you defined this pool?

As per the url_regex comment above, I do not think this does what you
want..

There is no use of defining a higher class pool if the per-user limit is
identical to the global limit. You would get the same effect using a class
1 pool here as you have defined the global limit to 1250 and each single
user is allowed to use up to 1250...

The last lime will never be reached as the first two lines matches all
requests.

What is your goal with these lines?
