They are running the service as mentioned. But its taking over all 14hours to reach mysore to hyderabad.. Which is slower than other operators. 6PM they are picking at Mysore and leaving bangalore by 12Am. Till 12:30AM you can't sleep on the bus, they keep the lights ON and keep stopping 100 stops around the bangalore.
I would not suggest this travels to anyone from Mysore to Hyderabad. You can use it, if you are traveling from bangalore to hyd.
Apart from that, vehicle cleanness and staffs are perfect as it should be. Nothing wrong in it.
