That seems confusing. If I say my new service is orders of magnitude more efficient than previous services, I don’t mean any thing about scaling but current performance, and I wouldn’t say orders of magnitude if it was just twice as many calls/second/core, but more than ten, or really more than 30, halfway between ten and a hundred, logarithmically.
Something that scales geometrically might well have some giant constant so it isn’t useful until a specific performance regime.
