The rules on Page 55 (New PDF version), states that worlds with Greater/Lesser gravity than Earth's can impact Mechs/Vehicles movement etc.

My question is...when? The rules here are kind of vague.

Example. Nanking has a Gravity of 1.06 (and in the TOTAL CHAOS campaign scenarios) States to use the High Gravity rules from TacOps.

But, with a low change to Gravity as 1.06, it is not until a Unit has a Walk/Cruise Speed of 9+ that any impact is seen.

The Rule:

To determine a unitâ€™s movement rates as affected by gravity, divide its Walking (or Cruising) and Jumping MP by the G-rating of the world and round to the nearest whole number (round down at .5).

Walk 7 / 1.06 = 6.6 = 7 (round up)

Walk 8 / 1.06 = 7.54 = 8 (round up)

Walk 9 / 1.06 = 8.49 = 8 (round down)

Worlds Like Detroit (gravity of 1.02) which means a unit needs to have walk/cruise of around 25 or 26 to see a movement impact.

Next would be Jumping Damage. The rules state:

Make a Piloting Skill Roll, applying a modifier for every full 0.5 gravities above or below 1. For example 0.2 gravity would apply a +1 modifier, while a 2.6 would apply a +3 modifier.

So, worlds like Nanking or Detroit, even with the miniscule 0.06 and 0.02 would impact jumping movement.

Using Comparisons to Planets in our own Solar System, Mars has a Gravity of 0.375 compared to Earth's, so a 100 lb person on Earth weighs 38 lbs on Mars, or that 100 Ton Mech is 38 Tons on Mars.

Using that same analogy, that 100 ton mech on Earth is....100.06 tons on Nanking and 100.02 Tons on Detroit.

In other words, is the 1G cut-off for High/Low gravity a little off? Shouldn't the cut-off be a little more?
