Unless you keep your chlorine levels on the high side, or even higher, in Ben's Best Guess CYA chart then your high bather load and debris can certainly consume lots of chlorine and generate a lot of chloramines that take time to break down. With such an overload situation, you can either shock periodically as you are doing or you can operate at higher chlorine levels all the time. Sliminess in the pool is usually more related to algae starting to form than to chloramines (and you said you had CC measure at 0 and probably don't smell chloramines either). So perhaps your chlorine level is on the low side given your particular pool situation. Just a thought. If you post your numbers, especially FC, CYA, pH, then perhaps this will give us some useful info for a "heavy bather load and debris" situation.
