The PractiScore app for Android allows to configure the squad rotation between stages.
This can be used to setup the IROA shooter order used in IPSC, as well as more elaborate squad rotation. E.g. when a range/bay has several small stages where the squad is split in half and both stages are run side by side.
The “Squad Rotation” setting need to be configured on each stage in the match. It is a number of shooters to move to the bottom at a given stage. So, the IROA order can be set as shown in the example below.
