Hi all,

I have a workout that I do regulary and with my last analysis it struck me:
- on the 400 FS with pull buoy (directly after 400m warm up with 30 sec pause) I record a 1:40/100m SCM
- on the 400 FS with paddles (already 2k into the workout) I record a 1:50/100m SCM

Same PE for both sets.

I would think that for both sets, times should be closer together or the second set should be faster with the same effort (having paddles + the kick).

What would you conclude from that:
Am I missing endurance (the fact that 2k into the set my x/100 drops by 10%)?
Am I missing arm strength (same PE but slower with paddles)?
Is my positioning bad (the fact that I am faster with a pull buoy)?
Is my kick bad (the fact that I am slower with paddles + kick)?

Of course it could be a combination of all. My question is, what should be my next iteration to get closer to the solution and identify the weakness?

My progress: Managed to get my 70.3 OWS with wetsuit down from 34 to very low 30 within 2 years with a max of 2 workouts per week and an avg. of 6km/week. Yes, I could do more and to get it down to 27-28 I would need to do 3 or more WO/week but progress has been statisfying so far and I have a lot more need to work on my running.
