EdoArad comments on Beware point estimates of problem difficulty

nitpick while confused on first reading

I think $\delta \left(\text{\%increase in resources}\right)$ should be instead $\frac{\delta \left(\text{Total resources}\right)}{\text{Total resources}}$, or else I’m not sure how to interpret it.

Ah thanks, good spot. You’re right.

Another way to express $\frac{\delta \left(\text{Total resources}\right)}{\text{Total resources}}$(to avoid a stacked fraction) is $\%\delta \left(\text{Total resources}\right)$; i.e. percentage change in resources. I’ll update the post to reflect this.
