There's another variable.  Noise, manifested in bit errors, is about
three orders of magnitude greater in RF than in wireline.  The larger
the packet, the larger the retransmission when it fails the CRC check.
If you must, there are yet more variables such as the amount of FEC.
The more FEC, the fewer bit errors, but the FEC comes at a cost in
capacity.  

Multivariable optimization problem.  And some of the variables change
from moment to moment.
