[Ads-l] Could "check-ed" = r-less "checkered"?

[W Brewer]

ADSL 11 Oct 2016 (Taiwan time):

WG: << Heard "checkt pattern." I would have said "check-ed pattern." >>
JL: << Soooo nineteenth century. >>
Flourish Klink: << I've never heard "check-ed". >>
WG: << I've heard "checkt" countless times, just not as purely an adjective
in the phrase, "in a checkt pattern, " as is the case, here. In this
instance, a herpetologist was explaining how to tell poisonous snake A from
non-poisonous snake B, since both snakes looked like brownish-colored
snakes. "The brown and the tan scales of the poisonous snake are arranged
in a checkt pattern."
  Abstracting away from the dialect split, as someone in the audience
pointed out, this information was essentially useless, since getting close
enough to the snake to discern this pattern necessitated getting close
enough to the snake to get bitten, while still not being close enough to
discern the pattern.
  The herpetologist explained that, using a camera with a telescopic lens,
you take a photo of the snake and examine that. You don't try to examine
the snake itself. >>

would immediately epiphanize the obvious rhotic ~ non-rhotic variation.]

NW: << I didn't save Wilson's earlier message on the subject, and don't
have time to search for it here, but a thought occurred to me:
  To his previously noted pronunciation of "striped" with two syllables, he
added a two-syllable pronunciation of "checked". Just this morning, my dad
talked about getting his "stripe-ed" sweatshirt, so I told him about
Wilson's comments, and he wondered if maybe what Wilson might actually have
heard was an r-less "checkERed", which (I now speculate) he then
assimilated to a small pattern of cloth patterns plus a separately
pronounced "-ed". Wilson, thoughts?
