If you are their sponsor, or co-sponsor you should continue to train and support your affiliates no matter what their rank. If they are advancing faster than you it could be your training and support that is motivating them. by communicating with them you may not be only teaching them, but you can learn from them also, that is what makes a team. I would say the more that advance faster than myself is a blessing, because they are the ones that are headed for the top.
