What do you mean by "mix hybrid" do you mean the Pro Tools hybrid engine? Or you mean an outboard summing bus?

You don't get "more delay compensation power" Pro Tools ADC limits are 16k samples at 44.1/48 kHz, 32k samples at 88.2/96 kHz, 64k samples at 176.4/192 kHz

You need to work out what is going on.

Start simple and understand stuff. What are the latencies Pro Tools reports on each track as you add plugins/inserts/change routing, is that what you expect?

There are multiple latency/ADC comp bugs in Pro Tools that have been described on DUC many times. One bug happens with inserts that follow a plugin and LLM and allow sends to persist in LLM enabled. You'll see unexpected latencies of few x 1024 samples for a H/W insert. But these bugs don't cause most user problems... that's more frequently just using plugins with huge latency, or bad routing etc.
