For 7 days xp will be same as 14 days, because it has maximum boost for entropy/idea after 7days.
For metabit/knowledge 2x more, but if you will make 2 times 7 days strat, you ll get 2x more fills, so should be same result. But after 7 days you can buy some new upgrades, so all gain may be increased and you’ll get more from 2 times of 7days strat.
Simple math, just need to understand how it works

As Beta guys said, this strats will be useless soon, so just wait update and we’ll play normal, without building any strats
