No, this almost certainly stems from the inherent inability of Indians to think ahead (as called out to me by my Indian brother-in-law and several other acquaintances). Dassault didn’t help when they submitted a bid that likely only consisted of the initial delivery cost of the fighters, rather than a full bid including estimated maintenance etc, but it fell to MoD to make sure of what they were getting, and MoD dropped the ball.
The ‘life-cycle cost estimations’ were entirely the purview of the Indian MOD so all the bidders would have had to have check identical/similar parameters for their bids to qualify. Its not like Dassault could have submitted data, which used different indicators when compared to Eurofighter.
