Macro to run formulas for multiple ranges of data in a spreadsheet to summarize data in the first blank row after the data summaries

[maxf24]

I have data history information and two blank lines after each sample there could be anywhere from one sample with 9 rows of data, or there could be 50 samples with 12 rows of data each.

When I receive the data, the first row after Data Samples BLANK, in this case row 12.

But in the first blank row at end of each sample of data i want to have a macro to automatically process data to summarize the the data samples using the following formulas.
F12- Formula is Sum(F2:F11)
G12- Formula is Max(G2:G11)H12- Formula is Sum(H2:H11)I12- Formula is (H12/F12)J12- Formula is (F12/(G12*8760))
* The ranges change
F26 ​ Sum(F14:F25)
G26 Max(G14:G25)
H26 SUM(H14:G25)
I26 (H26/F26)
J26 (F12/(G12*8760))

Example of what I'm trying to achieve. Could be 1-50+ data samples
Row | Column A B E G H I J K L N O P
