I've not flown a Maule, and only have about 250 hours in tailraggers, so Mr Maule may have the advantage of me, but myself, I think you aren't competent in any taildragger until you are fluent in both 3-point and wheeler landings in it.
I have never flown a tail wheel airplane that could not be wheel landed.
I would never check out any pilot in a tail wheel airplane unless said pilot was competent in both wheel landings and three point landings.
Myself I prefer the wheel landing almost all the time.
As to approach speeds in gusty conditions if you have to add airspeed to the normal airspeed you use trust me using math to figure out you need 63 MPH or what ever is over kill because no one I have ever met can fly that accurate an airspeed.....hell the needle is to wide to be that accurate.
