Like many have mentioned it's a lost of time if you compare to the gains you might get from
the time invested.

Is it a waste having a good kick in Triathlon? IMO absolutely not especially for FOP!

Why? for these reasons: (Starts, Close and Open gaps)

- You want to clear as many swimmers from you feet at the start as possible! Sometimes
just creating that 5-10m gap is enough to drop those weakers swimmers that might hang
in there!

- Closing a gap with a group in front of you, that extra speed for a few seconds might cost
some effort on the short run but you will save more by catching the draft.

- Opening a gap after Buoys, just turn on the after burners and surprise the guys behind you
and drop them!

If you are in a Racer mode (Top place in your age group) you want to have this tool in order
to react to the dynamics of the Race, again that's my own opinion and they way I like to Race.

I haven't been much in the pool and haven't done much of kicking but...
When swimming around your time 25-27 mins for 70.3

My kick sets times were:

25m getting in 23-24 sec leaving on '30 if I do all-out sprint around 20-21 sec
50m getting 48-51 sec leaving on 1'00 if I do all-out sprint around 44-45 sec
100m getting 1'45-1'50 leaving on 2'00 if I do all-out sprint around 1'39-1'41

I only start swimming when I was 17-18, so NO youth swimmer background!

Last thing, I use to love kick set and hate Pull set (always getting drop by others)
