Yep on the soft place, but it was the old 1/4" masonite. I think MDF is harder as is 1/8" tempered masonite. The good thing is if it goes a little deep, you can bondo it(never tried this) or move your (new)template a little and recut.
When you get your template done, bend a good metal yardstick or a pc of .050 glass around the curves, this will show flats and bumps you didn't see.
Good luck, take pics , and have fun!!
