How many sky q mini boxes?

[Sheetmaself]

Good morning, I have the SkyQ 1tb UHD box and have seen that this allows me to have up to four mini boxes plus the main one.

It also states I can play from 3 at a time.

I cannot however find out for certain if that is:

1) The main box plus 3 mini boxes.

2) The main box plus 2 mini boxes.

3) Main box on standby plus 3 mini boxes.

Any guidance as to which of the above would be great as I have had different answers from SKY.

Any 3 of any of the boxes at any one time. If any box is not switched to standby it counts as one.

We've got a SKY Q 2TB and 3 mini's. Unless it's changed since I took out my latest contract 18 months ago, it's the main box plus any 2 of the mini-boxes.
