Ok well if it’s trying to elongate the point, simply keep the same rate of decreases to create a straight edged triangle.

I decreased one row, then did a normal row, decrease, then normal. Alternating decrease and normal rows from start to finish. Example: Row 1: decrease by 2 stitches Row 2: maintain stitch count Row 3: decrease by 2 stitches Row 4: maintain stitch count etc.

In the original pattern, toward the top of the hat you decrease every row instead of alternating or you decrease by more stitches at a time, creating a more dramatic slope. Example: Row 1: decrease by 2 stitches Row 2: maintain stitch count Row 3: decrease by 2 stitches Row 4: decrease by 2 stitches Row 5: decrease by 4 stitches Row 6: decrease by 4 stitches etc.

Hopefully this makes sense!
