My hook says size P/11.50mm

I crochet tight and normally I would increase my hook size by 2 hooks but when I did the gauge this is the size that worked closest, stitch count was right but row height was still off so will need to compensate by adding rows. When I attempted to select a P it only showed the N/P/10.00mm so maybe that explains my need not to increase it.

I did not count ch 2 as first st in the cocoon part of this pattern. I also changed the ch 2 to a ch 3 in the hood.

I had to add 3 rows to reach desired measurements before hood.

Pattern took less than 2 skeins of Fleece and less than 1 skein of Barley
