Memory profiling with Scout and Xcode Instruments

Hi,

We are doing some memory profiling on our app, its a rather big app with a lot of assets.

The tests are being made on a iPad Mini, iOS 6.1.3, Air 4.0(latest from labs).

With Scout I'm seeing a stable 69mb of ram and 27mb of vram, which is expected.

But with Xcode Instruments it rarely drops below 200mb..

Is there something I'm missing or is that correct? It feels like quite a big diff.

Thanks!
