Passing depends on handling a lot. If passing is lower than handling, then it will increase faster.
But note that the passing training also trains HA and DR a bit. So it may be that elastic effect doesn't do anything special, except redistribute training a bit. For example:
Higher HA case:
90% goes to PA
5% to HA, 5% DR
Lower HA case:
70% goes to PA
15% to each HA,DR
The numbers are exemplary only.
