It is ordered. I need to split this list into 1., 2., 3.
segments based on the first element of each sublist, removing any segments that are smaller than that, e.g. 1., 2.
. I want to end up with something like this: {{{1., 1812.}, {2., 10076.}}, {{3., 4762.}}, {{1., 4262.}, {2., 5059.}, {3., 5860.}}}
