Better VE table resolution
Without changing backwards compatibility to much this is how I suggest its done to save on space (this is the minimum needed to even bother with this)
We will need 2 bits for each reference cell in this reference table, total is then 336bits or just 42 bytes, no need for axis as they are the same as the VE table
Each cell reference being 2 bits can have 4 total values
0 = 0 (00)
1 = 0.25 (01)
2 = 0.5 (10)
3 = 0.75 (11)
The VE number therefore comes from two tables
VE Table + Reference table
VE = 50 + (reference*0.25) = total VE value
With 1568bits(196 bytes) we could have a 0.142 resolution
Why do I think this is needed? because Alpha-N VE table is just not good enough even doing a fudge and halving the req fuel value or scaling so that 255 is the highest you´ll ever put in,
Lowest numbers usually seen in AlphaN tables is abour 30-35, 31 is 3.33% higher than 31. Thats quite alot for just one value, its still 1.6% if you half the req fuel. With just 42bytes we can improve this alot.
