K+ current in skeletal muscle

[Mark Fry]

Adrian, Chandler, and Hodgkin (1970) described the action potentials of
frog sartorius muscle and fit the currents to the HH model with m^3h n^4
kinetics.

They reported however that The K+ current had a reversal of 20 mV positive
to EK.

Does anybody know what the eventual explaination for the was?

An idealist is one who, on noticing that a rose smells better
than a cabbage, concludes that it will also make better soup.
