I think most would agree that it is wise to avoid burying the nose in the work, so your max cut is or should be limited by the bar length of the saw.
Respectfully, I have to disagree.
Y'all are either gonna learn how to use the saw and all its capabilities safely, or you're not and probably shouldn't own one at all. The in-betweens will get you hurt out there in the dark rain under headlights trying to clear storm damage so your elderly neighbor can get to the doctor and all the pros are tied up with powerline repairs.
Cutting logs deeper than bars is a common task in most parts of the country, and you should master keeping the nose higher than the powerhead as a matter of habit. Do you have to learn to make the plunge cuts professional fallers use to test for trunk rot? No, but the bar control techniques required for deep logs are the safest method to cut any log, and if plastic falling wedges and falling axe to drive them with aren't in your emergency kit, they should be. Storm-fallen trunks can be hard to read, and mastering those will minimize the chances of getting your bar helplessly stuck with you the only saw clearing the road.
It's touching the the upper quarter of the bar nose to the log that causes kickbacks. Avoid leading with the nose. When bucking a log from top to bottom, keep the nose slightly higher than the powerhead all the way through the cut. When bucking a log from bottom to top, keep the nose slightly beneath the powerhead.
If there is any doubt about the kerf pinching the bar, once the bar is sufficiently deep drive a wedge behind the bar so the saw can be freed if the log moves the wrong way. Once the saw if free, resume the cut from the opposite side of the log.
A plunge cut is made beginning with the lower part of the lower half of the bar nose until it's firmly captured a few inches deep in solid wood then gradually rolling the nose to the upper part of the nose's lower half and pushing the saw in like a sword.
““Perhaps then, you will say, ‘But where can one have a boat like that built today?’ And I will tell you that there are still some honest men who can sharpen a saw, plane, or adze...men (who) live and work in out of the way places, but that is lucky, for they can acquire materials for one third of city prices. Best, some of these gentlemen’s boatshops are in places where nothing but the occasional honk of a wild goose will distract them from their work.” -- L Francis Herreshoff
