GRP: Factor

MIN.VAL: num
MAX.VAL: num
VAL2: num
with several rows per GRP
where dp[i-1, MAX.VAL] dp[i, MIN.VAL]
within the same GRP.
I want to create df[i, VAL2] -

group. If this is true in practise, then you may want to check and
report when VAL is in the discontinuous region.
Here is my solution that ignores that (and only uses MIN.VAL and
completely disrespecting MAX.VAL). Not very
