A question

The problem with JH abuse like this is it is technically shield running.
All during the timeframe of making the jump your shield is regenerated.
You could enter a JH with no shields at all and exit the jump at full shields.
So by game mechanics it is the same as shield running in the fact that you are using a tactic solely for regenerating your shields. Or maybe a better example is someone loses a fight and then will not leave the system. Even if you manage to find and kill him he is still able to remain in the system because of game mechanics.
