*Freelance Traveller*, there was an article about the 100-diameter limit and an alternative way of calculating it by using mass instead of diameter as a basis. Link to the article: https://www.freelancetraveller.com/feat ... ddiam.html

I liked the article a lot and considered using that in my own campaign. However, when I tried using the formulas given in the article to calculate safe jump distance from a star or planet, I get very different results than given in the article. Granted I am lousy at math, so most likely I have made a mistake somewhere, but I cannot seem to find out where. I plugged the formula into Excel and let it chew the numbers for me, but no joy. I'm still getting different results. Could someone, please, check my math.

The formula in the article --> Safe Jump Distance (km where g=10^-10 m/s^2) (M=world mass in kg; uses modified relationship): D=(3.369×10^-11)×M^1/2.7

When I run that through Excel, using the mass of Earth (5.97x10^24 kg), I get D = 7.44923x10^13 km, which is a

*whole lot*more than 1,292,143 km given in the article table.

Here's how I entered the formula into Excel --> =(3.369*10^-11)*(5.97E+24^1/2.7)

What am I doing wrong or is the formula in the article wrong, perhaps?
