One limitation and improvement you should all write down no matter what the question is:

They're always going to ask you to find the proportionality of two things.

Limitation: Two readings are not sufficient to determine proportionality between [variable X] and [variable Y].

Source of improvement: At least six readings should be taken, a graph should be plotted, and proportionality should be determined according to the gradient of the line made from the six readings.
