How do we know it’s got a low reach, it’s on practically every platform I think, ie where is the one in ten figure come from ?

The figure comes from the BBC Annual Report and reach refers to 'UK population who use the service (for more than fifteen minutes) on average per week'. When widened to just 3 minutes with the service, the figure is still only 13%. It's not nothing, but it's very clearly a low use service and one that doesn't particularly carry out any unique functions at that.
