Normal Parker Drop?

[Sam Hershfield]

I've got two Parker 12 Gauge VH's that according to my measurements both have a drop at the heel of 3" and at the comb of 2".

Another collector warns me that " 1 3/4" x 2 3/4" is the most most people can handle. 1 1/2" x 2 1/2" is the prefered dimension by most shooters".

I laid the guns upside down on their ribs and measured down to the table surface. Did I measure incorrectly or is he incorrect? Thanks
