Gary, based on the picture, I'd say it has a combination of conditions. The crest is a bit large, the standards are a little short (in proportion to the falls) and it appears they are a bit relaxed or open. Each may contribute to what you see as stumpy. Notice I didn't say, 'problems.' Most will not see this as a problem. It's a lovely bloom.

This flower is either short & fat hence it's name STUMPY - or it has the largest style crests I have ever seen - you decide . Sort of makes it an interesting conversation piece in the garden ( even if I'm talking to myself ) .
