More training less results?

The last time i felt this way was like two days before national schools in 1998. Damn. I feel like i'm putting in more effort but i'm getting worse. I guess i can attribute it to my changing my strokes for supposedly more efficient and effective strokes. But i can't help but feel that my timing is sliding. Anyway, went for a swim this morning, 200 warm up, 1500 easy swim (37min), 4*100 Pull buoy and 4*100 (50kick, 50pull) with pull buoy of course. 100 cool down. Not too shabby. But, i think i doing too many easy swims. Too much junk miles? Not sure. But will push harder at next training. Back tonight with running training.
