random match with constant roles

[Ilaria Freddi]

Hi classex team,

I'm trying to use the code you published here ://classex-doc.readthedocs.io/en/latest/Develop.html#matching to implement random match with constant roles.

I used the code you posted in the lecturer section (update every 1 sec) of the first stage of my experiment.

The experiment consist in 5 stages with a loop of 4 rounds between 1st and 4th stage.

In test I made I saw that groups where changed only between first and second round. For all the remaining rounds groups remains the same.

Is it possible for you to help me understanding what it's happening and why it's not running well?

Do you need further specifications for it?

Thanks for your help,

Ilaria Freddi
