- if you have cheap, mid-range and top-end cars then you want to generate the same prices by setting the cheap price and having the values as 0, +1, +2 or by setting the mid-range and having -1, 0, +1 and that means plus and minus need the same ratio
I'm not sure I understand this last section. Unless you mean that you'd have three different baseline prices depending on whether we're looking at cheap, mid-range or top-end. I was thinking that the cheap, mid-range and top-end prices would be generated by the system, not that I'd have three different baselines for a product and start from there with the QREBS alterations
What I mean is that if you designed a mid range vehicle for 100kCr and calculated that the
-1 cheap version was 80kCr and the +1 expensive version was 120kCr, then I'd expect that
if I designed a vehicle where the base model was 80kCr, the +1 expensive version would be 100kCr and the +2 very expensive version would be 120kCr.
Otherwise if you design vehicles by designing the base model and then using improvements, I design vehicles by designing the mid range and then using a improvements and downgrades
and someone else designs top end vehicles and just uses downgrades, then we will disagree
on the price ratios, which makes it harder to use other people's designs.
