Exactly which is why I said 99%.
Most common training types its a solid bar which actuates them both at the same time.
And there is zero problem using them in the turn.
I say again
The no flaps in the turn is an old wives tale to enforce an instructors personal preference. A lot of the time because they personally struggle while doing it maintaining the flight profile.
The enforcing the no flaps in a turn in a common training type is just an indication of a talent limited instructor forcing their own personal belief down peoples throats. Usually the trying to retrain the pilot away from it screws up their normal circuit and causes way way more issues confusing them than the none issue which is deploying flaps in the turn.
