Quality speed modules are also efficiency modules

[wanne]

I assumed quality_affects_energy_usage+allow_consumption is kind of a way to prevent energy surplus loops.
But there is a catch: Rare speed module 2 and 3 have higher speed multipliers than energy multipliers. So event without modded modules you can get better efficiency.
In theory you can do that even with 4 common productivity module and 1000 uncommon speed beacons since effect percentages are stupidly applied additive instead of multiplicative. But this very theoretical.
Is there a nice way to prevent such things?

I think you can make consumption affected by quality by setting this property to 1.0 https://lua-api.factorio.com/latest/pro ... multiplier
