If we get a strange claim like "The 737 at MLW should have a stable approach speed of 170kts, with 70% N1 and 5 degrees of pitch", then asking for a source of information seems pretty reasonable here...

They usually don't find it because it is based on "shower curtain" type of sources. ("my brother told me", or "this other sim behaves this way")

I do - surely you know how much time is wasted on pointless and unmotivated debates (e.g. on whether or not an airliner can do a barrel roll)
