Fixed Gravity Values

• Divided the values by 10 as they appear to be a factor of 10 too large for some reason (compared to the system map + EDSM).

Fixes #124

I want to say I've seen this happen before, not with this program but in the past. Where a value in the journal had to be adjusted. Could be for internal reasons why they have the value like that, but be wary of any updates, if they "fix" this.

Well it's a simple adjustment to the html if they do..

Indeed. I had to backtrack and adjust for game updates before on my custom Voice Attack scripts, just because they changed a minor thing they did in the game. Once you know it's there, it's easy to fix, but chasing that bug not realizing it's not you but them that changed is frustrating.
