You're correct. Loads of variables. But, if you have more lean available, you can add it (decreasing radius turn). It's just a mental block because you don't want to hurt yourself, or damage the bike. Most modern sport bikes will drag the factory foot peg in ideal conditions. It's amazing how low they will actually go, but the lower you go the greater the risk. At 50% lean, you can hit some debris and the bike will slide a little bit and you'll recover. At full lean, that little loss in traction is the end of your day.
And I never have that feeling. Once I set in on a turn, there's usually a lot of adjustment (on the street) to avoid holes, paint, steel access panels, etc.
Try this on a stretch of road you know well. In a lane, there are basically 2 tire grooves. Start your turn on the inside groove, let it run wide to the outside, then back to the inside groove. Basically the reverse of what a racing line would be. Just to prove to yourself it can be done.
