Only the strongest station is decoded when there are multiple callers, or the 
operator uses his/her skill to time their S&P call.

Multiple stations come back simultaneously and are decoded. An algorithm in 
WSJT-X picks one of them.

Do you really like the idea that your station, that you have been improving for 
years to be loud, can now be selected against by a K1JT algorithm that chooses 
the weakest, not the strongest calling station ?
