Adding a slight twist to Factorio's technology system, ongoing research now slowly loses progress over time. No longer can you AFK on a trickle of science packs to carry you into the end-game. The more SPM you have, the cheaper researching is.

If you like science cost multipliers, you might like this mod.

Features:
- Configure the SPM drain rate, whether flat or relative to science cost
- Doesn't drain science from non-multiplied techs, such as Automation (unless you want it to)
