Unless you are talking about the thousands of military aircraft just flooding the MTR’s

I don't think you can quantify how many aircraft are operating at or below 400 feet AGL on a given day. So absent that kind of data, you have no way to support your statement that "generally" they're at a specific speed or below.
On the other hand, MTRs are plentiful, spread throughout the country, and used by some non-trivial number of aircraft each day, operating well below 500 AGL, and "generally" well in excess of 100 KIAS (on VR routes specifically).
