[quote=@13org]But again... The feedback wouldn't matter that much, since she has her main augment 'turned off'.[/quote]
I was thinking of it more that the central processor for the augment would just be working on the signals being relayed through the ThirdEyes, rather than the sensors in her body, but the system itself would still be fully functional and therefore susceptible to interference and feedback. Having said that, simply switching off her local system would prevent the feedback entirely, but would severely limit her local perception.

Is there any 'reboot delay' for switching between her systems at all? If she did shut down the core augment, how long would it take to get it back up and running again? Is there a period where it needs to 'warm up', giving a less clear reading or a more limited range as the system gets back upto speed, mapping and categorising the local area?

[quote=@13org]While focusing on the Third Eyes, the perception range on her augment is lowered to 7m. While under these specific circumstances, any Third Eye within a 45m area suffers severe interference from Anya's augment, rendering them useless.[/quote]
That could be explained by the increased signal sources requiring greater processing power for Anya's augment to filter through all the data it's receiving, reducing the efficiency of the local scan.

You could even take it one step further, with the effect gradually scaling with each ThirdEye deployed. This would mean that one or two might only reduce her local perception range by a couple of meters, but by the time she's got five or six running at once her processor would be overloaded, reducing her local perception down by 10 or 20 meters.
