I am so confused!

OK, Forumites, I need help figuring this out... :help: I am a breaststroker, for sure; definitely best at the 50. It goes downhill from there, according to how my times fall on the (outdated, I know) 2010 Motivational Times Charts. Since I have always been a speedster in general (definitely a rabbit, rather than a truck), I thought of myself as a sprinter. And, my 50's in all strokes rank higher than my 100's and 200's. BUT, my coach declared me a true distance swimmer, after I swam my 2,000 fly (and felt better at the end than at the beginning), negative split my back-to-back 3k and 1k open water swims, and negative split my 400m free and 800m free races on my first attempt. He also whips me on the first half of our training sessions, but I get stronger and start negative splitting during the second half of our 4,000 yard workouts. More evidence: According to the Motivational Times Chart, I rank highest in the 50 and 1650 freestyle and poorest in the 100 and 200. So, what gives? I'm best at the extremes, but, even when I correctly split my 100's and 200's, they :censor:. Any ideas as to why this is and whether I am truly a sprinter or distance swimmer? :dunno:
