Public math-geekery in case anyone's interested: I've customized my personal numbers to fBarterMin =
3.5365, fBarterMax =
6.2356.
Barring multi-craft exploits, the best non-skill multiplier you can get is 2.145: (haggle) 1.3 * (allure) 1.1 * (potion + enchant) 1.5.
I want the best possible buy/sell
ratio to be euler's number (won't go into the reasons for this here). Since the barter settings both multiply buy
and divide sell values, their effects are actually squared in practice; so my 100-skill buy value is sqrt(
e) * 2.145 = ~
3.5365.
Now, I want the total effect from skill to also be
e. Again, I want to see this in the buy/sell
ratio, rather than the individual prices; which means I want the actual difference between minimum and maximum skill to be sqrt(
e) once again. Multiplying this by the previous value yields ~5.8307. However, this isn't quite right: that's the ratio at zero skill. You start at 15. So we adjust by taking the difference, converting it to be the difference from 15 to 100 instead of from 0 to 100, and adding that back to the minimum value.
5.8307 - 3.5365 = 2.2942
2.2942 * 100 / 85 = 2.6691
2.6691 + 3.5365 =
6.2356This is actually less punishing than Phitt's "Easy" version at low skill ranks (though very close to Sensitive), but midway between Medium and Hard at the top end. The idea that the Speech perks are worthless honestly astonishes me, those are enormous benefits when you consider that they're multiplicative with everything and that their effects are squared in practice... though increasing the raw scaling from skill makes them significantly
less valuable.
Edit: D'oh, I forgot the Volsung mask! That's +20% in the potion/enchant group. Correcting for this, my results would be min =
4.008, max =
7.067. (Geekery indeed. Sane folks are probably safe with 4 and 7.)
Edit 2: I swear, this has got to be something like the 20th time I've wondered if Bethesda secretly hired me to come up with numbers and I just didn't tell me about it... take the process above. Leave out the gear/potion modifiers, only use perks. Don't perform the 100/85 conversion. And instead of sqrt(e) * modifiers, do sqrt(e * modifiers) -- something I did, before realizing it was a mistake. The results: min ~1.97, max ~3.25. Round to tenths: 2.0, 3.3... the vanilla numbers.
