This disc bears the description "a bio-rhythm analyser for the BBC Micro B" and before we go any further I feel that I should admit to being a great sceptic about such things.

The program has a long introductory sequence giving a full description of its facilities and its basis. This is required for there was no documentation supplied at all. There are even references to books that you might like to consult.

The title refers to the various types of group dynamics that you can analyse using the programs. There are graphs for individuals and numerical data for groups. You can even check up on certain notable dates in history and the rhythms of the people involved.

However, there is little to the program excepting the presentation. It's not much more than the bio-rhythm program supplied with all BBC machines as part of the Welcome package.

There are also a couple of niggles making the package more difficult to use. There is no record of the date taken from program to program. This means that for each rhythm you wish to display you must keep inputting the date. Just a simple line of Basic could have avoided this.

There is no error message reporting either. If you cause an error then you are sent straight back to the main menu without any explanation.

Overall, this is a specialist package that will appeal to very few.
