Using grousers as the example, they improve “ability to maintain speed” by 10% as the baseline, and by 15% if they’re in the mobility slot. On tanks.gg, this results in 9.09% terrain resistance reduction as baseline, and 13.04% reduction in the bonus slot. How do these numbers get calculated?

As if grousers weren’t already useless (edit: when compared to a turbo), they’ve reduced their functionality even further with another ambiguous definition of what they actually do
