You could "start" your stopwatch with

 	exten = s,n,			set(STOPWATCH=${EPOCH})

instead of your extraneous answer()s and then in your "h" extension, stop 
the stopwatch with:

 	exten = h,n,			set(STOPWATCH=$[${EPOCH} - ${STOPWATCH}])

You could also use resetcdr(w) at the start of each option. This will 
create a new CDR with the time spent on the previous option at each step 
in your dialplan. By setting the option number in a CDR variable after 
each CDR is written, the time spent in each option can be identified.

Thanks in advance,
