I agree, it sounds like a good thing to practice - I haven't done it myself but would like to try it given the chance.
Interestingly tonyhalsall mentioned an AAIB report. Another comes to my mind of a low hour instructor who crashed due to a combination of paralax error from the RH seat and (I think) miss-reading mph for knots. Just something to be aware of if you're sit over there for the first time.
