Should I help a stuck sledder?

Hi Lori, I want to ask your advice on a scenario that commonly occurs when sledding.
Senario:
A group of sledders find a hill slope to high mark on. Stable snow ( slab verified by snow pit ) , no previous avalanche activity visible, wind lee side with some wind loading of snow but no cornice . no significant terrain traps. High marking occurs ( one at a time ) but the fifth guy get stuck half way up. He / she is not hurt or trapped ( just stuck ) . The question is – ” does someone climb the hill via sled to safe location and walk over and help the stuck sledder get the sled out ? ” I feel that unless the sledder is hurt – there is no justification worth the risk to endanger another sledder to help out unless the stuck sledder is incapable of freeing the sled after an half hour or so of trying by himself. I know there is a lot of variables in this scenario. For years we found ourselves in these situations ( and in more dangerous slopes ) where if a member of our group got stuck – we would immediately race up the hill to help the stuck sled and rider. We always help our group and other sledders ( not part of our group ) when someone is stuck but I am trying to find a different approach to this scenario. If some one is stuck in a creek or tree well then there is no hesitation – just go over and start pulling or digging. I want to tell our group that they have half an hour to get out by themselves before we consider going up to help. Also we are going to start carrying 2 way radios to help with this situation. Please provide your thoughts .
Regards, Chris
