RCX Light Sensors vs NXT Light Sensors

Has anybody found any definitive report on comparing the accuracy between RCX and NXT light sensors?

The Nanites did a few studies and found the reproducibility of RCX Light Sensors seems to be better (+/- 1) than NXT Light Sensors (+/- 2). Do you know a similar study has been done somewhere else?

If you like, please do the experiment and share your findings with us by posting it as a comment to the blogsite, or sending me an e-mail. If you like to write up a report, like the report on toeing the line, that is great too! I really like it if you can write up a report and share!
