Final Upgrade still x17/x10?

The reason for the small gold difference is actually quite simple. I'm not sure why, but instead of rounding down to the nearest unit, it rounds down to the nearest ten units. With that, every value matches perfectly.

Yes, but that's through rounding, which the server does not actually do. The formula seems to be quite a bit more complicated than just rounding down to the nearest tenths.

Meaning the multipliers are not exact.

Actually, it's more likely the reason is that the base repair prices are not supposed to be exact. The formula will round off any decimals in order to give the player an even repair price, rather than a fraction of the a gold piece.

There's a whole set of numbers that indicate the server is rounding. I didn't round the actual values... that's what they are!

• 83.521 => 80
• 250.563 => 250
• 584.647 => 580
• 918.731 => 910
• 1252.815 => 1250
• 1670.42 => 1670
• 1002.252 => 1000
• 2672.672 => 2670

Specifically, 918.7 comes out to 910 and 1670.4 comes out to 1670. This makes it very clear that the only thing that could be happening is every single result is rounded down to the nearest ten!

Decimals... the ones you can't see.
