I think it is three orders of magnitude.

"An order-of-magnitude difference between two values is a factor of 10. For example, the mass of the planet Saturn is 95 times that of Earth, so Saturn is two orders of magnitude more massive than Earth."

https://en.wikipedia.org/wiki/Order_of_magnitude

> "More precisely, the order of magnitude of a number can be defined in terms of the common logarithm, usually as the integer part of the logarithm, obtained by truncation."

    $ bc -l
    l(835)/l(10)
    2.92168647548360208478

That would make it 2 orders of magnitude by that method. Happy to accept that it's 3 orders of magnitude by the N=a*10^b method though. Either way, it's definitely not one.

I think the whole point of orders of magnitude is to be a back-of-the-napkin estimation of what's what.

"a new car is an order of magnitude difference in price compared to a used car" is appropriate even if a new car is 40k and a used car is 5k

Electric cars have two orders of magnitude less energy storage than gasoline cars, but newer ones are only one order of magnitude.

Since orders of magnitude are multiplicative, rounded to the nearest whole order of magnitude ~300× to ~3000× is three orders of magnitude.

I think it’s an unnecessary nitpick. One statement is general and the other is a specific, extreme example. “usually 10x, sometimes 1000x”, that sort of thing
