When I broke out my gear inch calculator I found that going from 13/49 to 13/42 (a 7T drop) would yield about a 16.7% difference. In your example a 2t drop yielded about 4% so I think we're pretty close.
Assuming 54mph at 7K going to a 42T rear should yield about 63mph which is about where I was hoping to be. I appreciate you chiming in with your maths.
