It's hard to initially understand how this mod affects weight and performance without going to the wiki to check vanilla values. It would be handy to just see them in the comparison table.

It gets even harder once you start tweaking those values though startup settings.
These tables only show resulting values from default 1.0x multiplier.

Indeed, but it would make for a decent starting point to understand exactly how much the mod changes weight and power.

I also removed fuel bonuses, making direct comparison only possible for coal/wood.

Indeed that makes it hard to draw direct comparisons.
