I have checked the numbers visible in game over the last few weekends (late nights) and there was under 30 at one point and the most was just under 50. I think it is very unlikely that they get 3 or 4 times the subs to those showing perhaps at most twice (I recognise many I see late night as thoseI see during other time periods.
The drop in numbers since the last patch has been noticable but perhaps is due to schools and university holidays being over.
