I have done some walkin apnea and i have noticed that when doing walking apnea all my times are much more simular than when doing statics. For ex i have improved from 1:32 to 2:27 in walking apnea but from 2:00 to 2:27 the improvments have been like 3-6 sec every session. And i have almost all the time beated my pb. But when doing statics then improvments are often bigger and i often fail to beat my pb. I dont really know why this happens. Any ides?
