Not a good starting point at all. It is so outdated that you won't be able to get any of those senior counsel anymore - e.g. Ram Jethmalani dead, Indu Malhotra on the bench & retired. Sandeep Sethi for 2.5-3.3? LOL, you wish. Multiply it by a factor of 3.
Should have referred to the thread about how much senior advocates make.
25Cr is too moderate an estimate. Misleadingly low tbh. If we go by your number only of 10L, Datar arguing 250 hearings in a year would make that much (and this is not taking into account any other form of income- conferences, settling briefs etc.). I am sure he is paid for more hearings in a year, among other sources of income.
Delhi - depending on the forum, you can get a good senior for 5-25 L per hearing for the SC / HC. MR, Dr should be around the upper end of this band. HS, GS, etc... may be substantially higher.

Fees - 10L (minimum) per Hearing excluding all other costs. Per year he will be making atleast 25 crore.
