That is the main flaw with partial panel practice. You know the gyro

You will know it pretty eimdiately, *if* you are not too lazy to
permanently do the cross checks. Cross check possibility is the reason
why you have all those "useless" instruments like VSI and turn coordinator.

OK, you obviously have no, or very little, experience flying single
pilot IFR. There are times when things get very busy and the cross
checks don't occur at nearly the frequency you might desire. And subtle
failures can be hard to detect in the early stages.
