Hey guys,

So I just recently did Game 3 from PT 62 as a Grp-chart game and got -2. Later I learnt that doing that game in a non chart form helps with not making mistakes.

So my question is, when you have two set of variables given with a certain number of spaces allotted for e.g. exactly 4 employees, Q,R,S,T each attend exactly two of the talks,F, G, H, I.

OR something like researchers H,L,P will learn at least one at most three languages R,S,T for e.g., how do you tell for sure whether to use a chart or not?
