Well that depends on your source. Coming from the ONT you will have a
stable and predictable cable signal. If it is very high or "hot", higher
losses (more splitters in series) will knock the signal down (closer to
optimum). However, if you start with a low signal level from the cable
company, you will want to avoid large losses.
It is very helpful to have the necessary test equipment to measure cable
and OTA signals. I have a relative in Boston and see if he can get his
Verizon ONT measured.

Considering that the attic/bedroom feeds are temporary, I would go this
route. Test the PVR-500 and see if PQ can tolerate the loss of the
additional two-way. When the other frontends are in place all you need
to do is disconnect the attic feed from the 4-way and replace it with
second coax you ran as a spare to the family room. You did run a spare
to where the A180 and STB are located, right? <nudge, nudge>

I have always had the best results by placing the cable modem (if
present) and any HD-capable digital tuners/STBs at the top tier of
splitting. The analog tuners can all come from one leg of the top level
and then treated as a separate entity. So, no I would not recommend
putting the modem after another splitter. Again, if your ONT is putting
out a hot signal, it may not matter.
