You've just buffed the maximum jump range from 45% increase to 70% increase, though.
Looking at Inara for the FSD upgrade and optimised mass the ranges are currently:
Grade 1 - 00% to 04% <-- I think this should start at 1%
Grade 2 - 03% to 14% <-- This is too large of a gap and overlaps grade 1 so you could see a downgrade.
Grade 3 - 08% to 25% <-- This is much too large of a range and has a large overlap.
Grade 4 - 11% to 35% <-- This has a very large overlap and it's range is even worse than the last grade.
Grade 5 - 15% to 44% <-- The overlap between grade 4 and 5 here is enormous meaning there's a very large chance you'll roll a downgrade.
To me as grade goes up the range should decrease, you are supposed to be getting a better, higher quality, precision upgrade. The ranges here are just the opposite.
I would do this:
Grade 1 - 01% to 14% <-- 13% range
Grade 2 - 15% to 25% <-- 10% range
Grade 3 - 26% to 33% <-- 7% range
Grade 4 - 34% to 39% <-- 5% range
Grade 5 - 40% to 44% <-- 4% range
Are those Inara figures just for the primary effects, or do they also take into consideration the secondary effects?
I'm surprised the overlap is so large; but I'd guess it makes slightly more sense if the secondary effects are already included. If not, then YIKES! Imagine going from a 35% Grade 4 upgrade - possibly with a further secondary increase - all the way down to a 15% Grade 5 - possibly with a further secondary decrease.
I would not be a happy bunny if I got that sequence of rolls. (4 rabbit's feet and still no luck?)
This is a prime example.Imagine going from a 35% Grade 4 upgrade - possibly with a further secondary increase - all the way down to a 15% Grade 5
I d put the higher variance at the high end, or keep them same sized. I dont think it makes sense to put such a low variance at the very top. Should still be worth it to keep rolling the level 5 recipe, as something to do. Just should always be better than a 4.
I think the system is fine.
The average improvement for any level is always higher than that of a lower one and lower than a higher one.
When you push the limits of an upgrade (and they are all higher than the original manufacturers can provide), you should expect a bigger variation of possible results (including bad ones) due to the difficulty involved with the mod.
If you get a great upgrade at a lower level you should be very happy rather than thinking that your chances of improving again at a higher level are reduced.
This is a prime example.
You might be happy with 35% on L5 (where the max is 45%) - but you should be even happier if you achieve that on a L4.
