The following article explains how to calculate tandem standards. There is also an online calculator which does the job for you - go to the calculator and click the "tandem" button.
Tandem standards are calculated in the following way.
NOTE 1: Do not take the average of the two ages - this will not give the right result (and will result in the crew being given a tougher standard!)
Example: A 25 mile with a mixed crew consisting of a man, aged 52, and a woman, aged 48:
NOTE 2: The tandem standard is meant to provide fair competition between tandems. Under VTTA rules it should not be used as a basis for competition between tandems and solos. (When we reviewed the standards we verified that the above method seems to work well for competition between tandems - we did not attempt to verify whether or not it could give a good comparison between tandems and solos. Anecdotal evidence suggests that the 10% deduction would give slightly too much advantage to the tandems.)
In the coming days we will provide an online calculator and a downloadable spreadsheet to help with these calculations.
