Fuji - not necessarily.
I can't see the flaps from the cockpit. And this was a very turbulent day and there was no way of getting reliable airspeeds or a tactile feel for how she flew. Also, my flaps don't have settings - it's one continuous application and you set them by a gage visually and it can be hard to see if they're deployed. And the reason you don't leave the flap actuator in the UP position (which would have solved the problem) is that if you get a hydraulic leak, that will drain the system (which controls brakes and everything). So you go back to NEUTRAL after every application.
