Bill,
jl0=. ;@:((<@:[ ,. ])&.>)
is probably the kind of solution based on each that you had in mind.
It (jl0) is
longer than Henry's
jl1=. ;@:(,.L:1"0)
but surprisingly is also leaner and meaner:
'L R'=. l (100&$&.>@:(,&<)) r
st=.7!:2@:] , 6!:2
1000 st'L jl0 R'
13184 0.000232441163
1000 st'L jl1 R'
30848 0.000286170726
L (jl0 -: jl1) R
