UPDATED: Double transfer changed to double impression due to feedback below.

You might want to read this thread; You clearly need to learn more about double transfers and their appearance.

Me thinks that perhaps we are getting punked?

Perhaps. I'm willing to risk a few posts.

This I believe is a poor plate wiping issue and not a double transfer. Much like this one...

This thread has pictures of quite a few double, and even triple transfers, for you to see examples of.

Double impressions are printing varieties.
Double transfers are plate varieties.

Ignoring plate wear issues, double transfers tend to be consistent for a given plate position. A stamp with some doubling that looks like evidence of a re-entry of a plate position can usually be proven to be a double transfer by finding at least one other corroborating copy.

Double impressions are one-off's during the printing process.

Right, sorry, I don't know what to call these. Double transfer / double impression / re-entry. If there isn't a catalog description I have a difficult time deciding on any of the criteria. Easiest is inverted and double overprints. Thank you for the link, I checked it out.

Given my limited knowledge on stamp presses and processes - shouldn't I just refer to them as a "re-entry" or "doubled" and be done with it?

Generally, if there isn't a catalog listing, I'm going to throw out one or the other and not look back.

To begin with, you should read the first 80 pages of the catalog, which will give you a lot of information.

And why would you "throw out" any stamps?

I'm saying I'd throw out one term or the other - as in "double impression" or "double transfer" and not look back.

Whole stamp doubled: double transfer

Portion of the stamp: double impression

What I'll probably go with: "re-entry"

While we're on the topic - what say you about this one? Color shift sound good enough for you?

You really need to do more research.

A lot more research.

I think the takeaway here, is that terms such as "double transfer", and "double impression" have very definite connotations. It requires analysis of a stamp in order to determine if it exhibits one of those.

When posting a stamp, you could refer to "doubling" or "extraneous ink markings", for example, that you observe. Those are observational terms, as opposed to the specific terms that you have been using.

Much appreciated txstamp!

I now have a Epson V600 photo scanner for these tricky stamps. I'm hoping to get all the detail I can at the highest resolution possible for these kind of investigations.
