Im not sure there is much of a difference between whether it is pairs or an indy. Although you may be with a person you have played with a couple of times, in individuals i find that often partners dont take it seriously at all, and if they are someone who automatically thnks they are better than you because they class themselves as expert and you as advanced, often they will angle the bidding so they get to play the contract, which can lead to a poor result. Also i find that individuals are taken far less seriously and people are prone to doing more random things than with pairs. In pairs, although you have a person you have probably played with before, so have the opposition, thus the standard of bridge will be most likely sounder and perhaps pairs are a more accurate result, who knows..
