You already have an excellent roll with your 53%.
In theory you could go a few percent higher, if you roll 50% on the primary and get lucky with the secondary.
Or you could stop obsessing over an extra 0.5LY (in an exploration build) and just play the game.
I'm not sure if those numbers are real, but I've had some rolls before this one and I can tell that even 5%
affects that range by quite alot, not sure about all the tips and tricks of an exploration build you're talking about,
but when you decide to go 25k ly away from a human inhabited space, those 3ly can turn into 300 after 100 jumps.
The more you know...
You shouldn't put so much importance into getting the highest roll.
It is affecting your enjoyment of the game, this grinding thing.
For the same reasons listed below, I would work hard to get that sweet-sweet high roll just
to not get bored (more than I could've) while I'm flying towards the center of the galaxy.
The only thing I have troubles with is datamined wake solutions, since they're very rare.
Other than that, grinding for the grade 5 become a vacation after the last patch.
There is no such thing as luck and randomness with seeded numbers doesn't exist either.
Well, I just need to sit down and wait 'till I get the seeded number above 53% and I'll be happy for the rest of the trip.
There's a rainstorm couped with shower of hail, but okay. Why not? [big grin]I want you to take a nice walk outside and enjoy your day.
