Which section of LU track has the most frequent throughput of trains
at the peak? I'm excluding sections where there is more than one track
serving the same direction of traffic.

Central Line in Z1, perhaps?

Have they got past 28tph?

I'm sure it was claimed to be something like 33 tph on the Bakerloo in
the 1970s. There were two branches then, of course.
