The way I see it, the whole mujhahideed, and then taliban, then csf and now again taliban support blew up in your face.
In 1947, you did not anticipate Indian Army pulling in - Thus another situational awareness failure.
In 65, your own military brass has multiple times indicted your military leadership of poor foresight. (let me know if you need references)
In 1971, the lead up to the war was your own doing, strategic planing is not just positioning your troops, it is conflict management fr long term scenarios.
In 1999, your own brass again on record says that is was an out come of 4 people planning Kargil.
I have no problems if you think that is the definition of good calculations. If so I wish you well.
Now coming to gist of what I said. If your defense policy remains reactionary to what India does or says, you wil always be a step behind. For every new doctrine India discusses if you have to some up battlefield solutions, it just makes you look foolish. Rather it would be prudent if you had a defense policy that would be able to contain every possible doctrine or battle formation that India or anyone can throw at you. My point was as simple as that.
