We are getting an error message Non-Standard Stroke, Not Supported for the relay events that are not the norm.

These are proprietary to Hytek and non-sanctioned by USA Swimming, therefore our system is unable to support them. This is true even if you are a non-USA Swimming team due to HyTek's file format. If USA Swimming ever adds those relays into their file format, be assured we will accommodate them.

You will have to manually add the swimmers directly into Meet Manager.
