India is hardly keeping its mouth shut. In fact, they are pressing (overcompensating) on their airbase missile strike narrative and deliberately ignoring the air to air component.
Which to me indicates that there was nothing good to share on that front so they'll never share it.
We know they lost aircraft. But how many, ultimately, can come only from their side.
Just 101 on air warfare - shooter's numbers sadly are just not credible.
He is susceptible to both mistakes(target mark lost), has incentive to make larger initial claims, and has negative incentive to roll claims back, especially when opponent tries silence as a public relations approach.
Like, ISI probably knew the exact number within hours(when indians themselves dealed with the confusion). But why undermine the public perception? India is so afraid of admitting the loss, you can be a bit more ambitious.
