I'm going to assume you are talking about a SERG and a SESG, since those are what your old posts indicate you have/had. If that's the case, the engine oil capacity is 4.0 quarts, not the 3.5 you mentioned. Of course, many of us only run 3.5 quarts to reduce carryover into the air cleaner, but official capacity is in fact 4.0 quarts for the Touring models.
When you drain the primary on the late model bikes, it is very difficult to get it drained completely, especially if you leave the bike level instead of on the jiffy stand. It's not uncommon to leave up to six ounces in the primary on some bikes. That's a good reason to actually check the level when you add the new fluid instead of just dumping in the full amount. You don't want excess fluid in the primary (clutch drag).
The engine will always have a small amount of oil left in the crankcase sump that can't be pumped back to the tank. It's normal to have up to six ounces remaining in the sump. Minimize this by letting the engine idle on the stand for a couple minutes before shutting it off, to allow as much oil as possible to drain down and be pumped back to the tank. Don't rev the engine, as that just pumps excess oil into the top end again.
Finally, I don't see in your first post where you accounted for the volume of oil in the oil filter. Unless you have a filter crusher, you will never come close to actually draining all the oil out of the filter. Probably a lot easier to just approximate that it holds a pint of oil and not even try to drain it and measure it.
Personally, when I measure the fluids I remove I don't combine them. If you really want to know how much you are leaving in each hole, drain and measure them separately.
