Won't - I understand you are coming from the perspective of IND winning probably 20-25 Tests almost non stop at home; but there is a difference. PAK won't have added more points if it was a longer series and I can categorically prove that.
Because, PAK's trick in UAE had been always catch tourist off-guard at the early stage of the series when they are still not accustomed in UAE. Once they are settled, most series had been much closer. Take a look - even during Misbah's period, SAF won 2nd of 2 Test series; NZ came back to tie it 1-1, after losing 1st Test by innings to in total 3-4 PAK wickets, WIN won 3rd Test, which IND's 3rd XI won't lose to this WIN at home in even 5 game Series. And, that epic series against SRL was not even one year back. This is considering that, in those loses - every time PAK won the toss, and PAK's most of the wins in UAE had been after winning toss - last time SRL did won both tosses and .... you know. Only team (Asian team) that is more accustomed in UAE condition that PAK have played in last 7-8 years are SRL and they have a winning record here - can't recall exact numbers, but I guess it's 1-0 (or 0-0), 1-1 & 0-2. Based on the trend, and law of average (for toss), I can say had most of those series been 5 Test affairs, PAK won't have been ever even close to top 3, and I am a fan of PAK cricket, Misbah as well - but you don't need to buy that, so you can ignore it.
Enjoy the series and I am also happy - PAK won the Test & series, but keep things in perspective & don't over do, otherwise you are risking to match minnow BD fans, who jumps like world champs with some win here & there.
Hope, now you won't remind me about BD's Test record.
