How do I avoid referencing hidden values in formulas like OFFSET?

I am using autofilter and each time I switch to the next entry I need to
capture the last value in a certain column to use as part of a new formula.
Let's suppose my filter shows me my headings in row one, data in rows 11-20,
and then first blank row (row 3100) below all the hidden rows. I was trying
to use OFFSET, with a cell in row 3100 as my reference in order to see data
in row 20, but instead I am getting row 3099. I realize that functions like
SUBTOTAL ignore hidden rows, but there are only 11 different applications of
SUBTOTAL. How can I add this useful feature of SUBTOTAL to OFFSET, or
something similar?

Add a column to the table that shows the row numbers, then use
SUBTOTAL(4,NewCol) to get the row number of the last visible row in the
filtered table. Use that with INDEX.
