Copying multiple conditional formats of an entire row to the rest of the spreadsheet

I've done this where I select the first formatted row, then use Format Painter and select the next row. Your format is now applied to 2 rows. Then select those 2 rows, and use Format Painter on the next 2 rows. Now you have 4 rows formatted. Double each time, and you'll reach 393 rows in 10 steps.
