I'm sorry but this is really ludicrous excuse.
What does it have to do with it???
Producing miners is a manual process not intellectual... I don't really see the logic here.
If you had no problem finding time to think what kind of sale offer for SP31 and advertise it then you certainly have had a plenty of time, within last 3 weeks to think about compensation options for October.

As I said, on top of the fact that we have not even had a chance to earn anything from our Group Buy miners yet, we don't know if there is any sense in investing in October batch, because we have no clue what your compensation will offer. This uncertainty forces us to lose early order, queue positions for October batch.
