Find First Value Greater Than X In Given Range Using Variables

My data has a bunch of near 0 figures followed by values I actually need followed by more irrelevant 0's than once again followed by values I need and again irrelevant 0's. Looks like

0.1
0.12
3.2
3.4
0.1
0.3
4.5
4.2
0.3
0.11

but with many more rows and numbers. I'm graphing the start and end values before/after zero's.

The first block of numbers I figured out using

=MATCH(TRUE,INDEX($C8:$C150>1,0),0)+7 I then index from that given row.

The span of relevant values I'm looking for constantly changes, so once my numbers deviate too much I stop, using another index formula.

Now for finding my beginning and end points for the next block of data I've combined using VBA with excel formulas. I can't quite figure this part out. I've created Variables for ranges and then used them to find max and min Values.
