Except, when a biomorph enters a simulspace, it is not done by means of making an infomorph copy and running it in the simulspace. Instead, they put a headset on, and the biomorph's brain is accelerated up to that speed. This is one of the reasons why I agree that 60x simulspace speed for everyone is somewhat silly, and if I were to see abuse in my games, I'd put in a limit of how fast a biomorph's brain can be accelerated based on the quality of the hookup hardware and supporting infrastructure (headset can only get up to 15x, but a full vat-job where they do essentially yoink your ego out of your brain and run it as an infomorph can get up to 60x). Infomorph and synthmorphs, obviously, don't have that problem. However, that still doesn't answer my question. Let's just say we limit it to 2x speed. Since the biomorph's brain is having its perception of time messed with, so that every one second that observers experience has two seconds going by for the biomorph's ego. If that ego is an async, they have access to psi sleights that allow them to mess with their own internal brain chemistry and information processing. So, if an async tries to use Downtime--an internal-effecting psi sleight--while their mental signal processes are being sped up to 2x normal, would it take 4 hours to complete, or 2 hours? My internal vote is 2 hours--with the caveat that using Psi-Chi sleights when in a simulspace either adds a significant penalty to the psi activation roll (perhaps equal to the simulspace acceleration, so trying to do it at 30x speed gives you a -30 penalty to the roll), or increases the strain (perhaps adding a strain modifier of half of the simulspace acceleration, round down, meaning that using Psi-Chi sleights is only safe at low rates of acceleration; high speeds could literally make your brain cook itself).
