Instruments ObjectAlloc Graph question

Update:11-30Source: network consolidation

Hello,
I'm in the process of finalizing my iPhone application for release. Right now I'm focused on performance tuning and hunting down memory leaks. I've been using the Instruments application to help find memory leaks and it has been quite wonderful. I was able to successfully fix the few memory leaks reported. I'm relatively new to using instruments and I did have 1 question about the ObjectAlloc instrument:
In general I've noticed that the CurrentBytes display graph of the ObjectAlloc instrument is always going up. It's not going up rapidly, but just slowly overtime during the use of my application. Even when some of my objects get deallocated it doesn't seem to make the graph go down. This seems wrong to me. The Leaks instrument is not reporting any memory leaks at this time. Why would my ObjectAlloc graph continue to go up? Should I be worried about this? Perhaps I'm doing something wrong or reading the graph wrong?
Any insight would be greatly appreciated.
Thank you,
-Keith

Thanks for the explanation Mark that is what I suspected but it helps to have it confirmed.
A second question. I notice that the Net Bytes and #Net are going up over time very slowly. It seems to ramp up at the beginning and then plateau around 8420000 bytes. After playing the game a few times more it may be up to 8430000 bytes or so. Leaks isn't reporting any memory leaks. Any idea what might be going on or how I may be able to go about tracking this down?
Thank you,
-Keith
