Not sure if this is 100% accurate but...
According to
Coriolis. Krait Mk II is technically ranked joint 8th (level with the Asp Scout according to the basic summary table) in terms of maximum base non-engineered and non-Guardian boosted jump range.
The top 8/9 ships are:-
- Diamondback Explorer at 41.61 according to build but 41.8 according to table
- Anaconda at 39.96 according to build but 41.4 according to table
- Asp Explorer at 38.01 according to build but 38.2 according to table
- Hauler at 37.29 according to build but 37.3 according to table
- Orca at 35.80 according to build but 36.2 according to table
- Dolphin at 35.10 according to build but 35.2 according to table
- Courier at 33.32 according to build but 33.7 according to table
- Krait at 33.11 according to build but 33.2 according to table
- Asp Scout at 32.90 according to build but 33.2 according to table
The Python for comparison purposes maxes out at 29.61 without a Guardian FSD Booster according to build.
With the largest Guardian FSD Booster that changes to:-
- Diamondback Explorer at 50.64
- Anaconda at 50.35
- Asp Explorer at 48.33
- Orca at 46.14
- Dolphin at 44.01
- Krait at 43.47
- Asp Scout at 43.11
- Hauler at 42.86
- Courier at 40.16
The Python for comparison purposes maxes out at 39.99 with a Guardian FSD Booster according to build.
Of course, all of these builds are without Engineering factors and that could shake the list up again. The Hauler/Courier positions are tentative - I see little point in this kind of theory crafting personally to waste any more time on it than I already have.
At the nub of the problem here is that we are dependent on the tools providing accurate information and as shown above there are discrepancies in the available data which means that one or more of the numbers could be wrong. Not only that but these builds would be of questionable value since they do not include a fuel scoop, great for proving some min-max theory craft but an abysmal basis for practical application.
Moral of the story: Only a fool would trust in numbers alone before drawing final conclusions.
