Just to understand you clearly, when you become a soda machine etc., and you are losing energy, this is manifested as a marked rise in SPL, right?
Right. For example: Last weeks I mostly swam 1-3ATPs. Way back I go down until my SR gets 3-4Strokes out of my green zone. Today (LCM) with TT 1.3s-41SPL; 1.24s-42SPL; 1.2-42SPL; 1.14s-46SPL.... all felt fairly uncomfortable...
