Note 1 - Krishna's age could easily be well over a 100 if you make him older when he killed Kamsa or if we extend the period of Jarasandha's invasions or if we take statements of Krishna meditating in Himalayas for 12 years for Pradyumna’s birth seriously. This is a very conservative timeline.
Note 2 - Vrindavana period is so short because if you read the Harivamsa you will realise that everything in Vrindavan is happening in quick succession. Kaliya, Dhenuka, Pralamba incidents happened in a single monsoon season and Govardhan happened immediately after.
