On weekends I think they have normal two normal ad breaks with 4 mins long of pure advertising per internal break and 4 minutes of and external break so that it makes 12 minutes per hour, at least before 8pm...messy strategy, either you have short internal breaks everywhere or you don't lol.

But, of course, it's much better for the type of channel Sky Atlantic is to have the shorter less frequent breaks kind of strategy, it makes the channel premium.

Sky Atlantic Italy is very similar too (I think there's no internal breaks at all), and Sky German entertainment channels have no advertising at all, to make pay TV look attractive.

While I realize Sky British channels have to compete with A LOT more channels, they try to make the ad breaks look slightly less invasive tha ITV/Channel 4 and a few others I've noticed: they're 3 mins long of pure advertising instead of the usual 3'30 and 4'00, and they have an external advertising break.

Sky Italian entertainment channels are in a middle position, as the breaks are normally just 1-2 per hour and at times there's no break at all for 25-30 mins long slots, on all channels.
And there's also no dependence on the top of the hour/half hour slots.
