Can we talk about how sleeping pad R-values are totally overhyped?

I read a post last week from some outdoor gear blogger who tested like 15 sleeping pads in actual winter conditions and found that most of the R-value claims dropped by at least 30% when temps hit below 20 degrees. That really stuck with me because I spent $180 on a pad last fall specifically for shoulder season camping and still froze my back off on a 35 degree night at Shenandoah. Turns out the test was done in a lab with perfect insulation on both sides, not on actual ground with a tent floor underneath. Makes me wonder if we should be looking at ground insulation layers and foam pads instead of just trusting the numbers on the box. Has anyone else found a pad that actually lives up to its R-rating when the temp drops?

Wait, so that foam-and-inflatable combo from @michael803 is actually the move? Crazy, I always figured pricier meant better.

Lab testing is basically worthless when your pad is sitting on frozen dirt inside a tent. Ground saps heat way faster than any insulated floor can block. Foam pad underneath a cheap inflatable worked way better for me than my expensive "winter rated" pad ever did.

Man that's rough, I feel you. Cold ground is no joke it just sucks the warmth right out of you no matter what fancy gear you've got.
