Default (L/D)max vs. minimum total drag

Hello all,

I'm trying to figure out whether or not (L/D)max corresponds to the minimum point on the total drag curve (i.e. drag vs. velocity). If you look at Page 2 in this thread, particularly posts #16 and #19, there is some disagreement about the topic, but it doesn't seem to have been fully resolved. Originally I thought that (L/D)max was independent of the minimum drag, since the drag curve does not account for lift, which is obviously an input to finding (L/D)max. Now I'm not so sure. Can anyone shed some light on this? Thanks!!
