Here's a comparison from Kamm's FKFS:
They had a crude Lay model with slab sides which had Cd 0.20 at this length.
Then they 'added' about 10% body width to 'bulge' out the sides,longitudinally and transversely,and the drag came in at Cd 0.16 with this fish-like shaping.
Running the tail all the way out to 100% of their 'template' netted Cd 0.12 when the nose and edges were softened.
