There isn't (or should not be) much disagreement about the current 
in a coil.  Quite simply, unless there is a significant loss - 
either I^2R or radiation - the current into and out of a coil must 
be the same.  After all, a coil is a passive device and can neither 
create energy (increase current) or destroy energy (make current 
"disappear").  

Your real effort should be to develop a model that will adequately 
explain the loss and/or radiation.
