That does not seem like much pressure. Really not too much unless you have alot of folks coming over to fish pretty regular. LIke you said though the bigger bass are harder to catch. THis is why you want to max out number of big bass so there are more to go around.

As far as feeding what kind of feeder is that? 12 secs if an Aquapro(used to be Stren) that is way too much food. How much food per week is that? Basically you want the food to be eaten in 5-10 mins. If 2 mins not enough if floating againist the bank 30 mins later too much. When tyring to feed to bluegill to grow more bass you need to fed 2-4 times/day (6 is over kill)for less time and in more places. Bluegill can not eat much at each feeding nor do they travel far. So you might need to add another feeder or tow if trophy bass is your goal.
