It might be a silly idea, but that’s what I do with my weighted blanket when I want it to be a bit heavier: I fold it just over my shoulders, and leave it single on the rest of the body. It doesn’t change the thermal properties much, but it feels better. So you could try a lighter weighted blanket (10 or 12 lbs), folded on the shoulder. The problem is that lighter weighted blankets are probably not necessarily cooler than a heavier one.

Buzz is a number divisible by 5 if you’re a programmer in an interview :)

But I agree, the numbers have to make sense. The problem is that there is not just one dimension (size would be the obvious one, but there can be SUV big (boo) and minibus big)

The engineering solution would be to simply make the number multidimensional when needed:

5 = sedan
6 = crossover
7s = bigger than crossover, but for SUV losers
7v = bigger than crossover, but towards being a van/minibus

Not as clean but better than VW Thingamajig Sport Edition. I don’t know a lot about car classifications, I would hope those names are kind-of maybe standardized
