B11R was launched in following routes by Kesineni:
Bangalore-Mumbai [Pulled out]
Mangalore-Mumbai [Pulled out within a month's run & deployed as second service of Bangalore-Mumbai]
Hyderabad - Ahmedabad [Pulled out recently]
Hyderabad - Cochin [Pulled out in Feb 2015]
Hyderabad - Coimbatore
Hyderabad - Madurai
Hyderabad - Trivandrum [Pulled out in Feb 2015]
So it sums up to 14 bus as you said.
Buses pulled out in Mangalore/Bangalore- Mumbai deployed on Hyderabad-Mumbai [2 services]
Then the bus pulled out of Cochin / Trivandrum as you said were deployed on Hyderabad - Mumbai 2 additional services; however this was not run for long.
Both were removed; 2 sets of B11R was used to upgrade Vijayawada - Hyderabad - Mumbai service and other remained as spare with running Hyderabad - Mumbai.
Then spare used on Hyderabad - Mumbai was diverted to additional service of Hyderabad - Coimbatore I guess when Orange Travels started Coimbatore service.
They have pulled out 1 service of Hyderabad - Mumbai and placed it on Hyderabad = Mangalore. Then recently pulled out Hyderabad - Ahmedabad is now put again as second B11R on Hyderabad - Mangalore route. Hyderabad - Ahmedabad crew were Ex- Hyderabad-Mangalore crew.
Thus brief history of service rotation by Kesineni of thier B11R's
