Aamir's all 5 ATG are Christmas release, Salman's Last 10 Hits in which 9 came from Eid/Diwali/Christmas, 1 Ready Non-Holiday Blockbuster.
Baahubali 2 is 1 exceptional case which can't be set as example for Non-Holiday release. This is 2nd part of Bahubali: The Beginiing which was big hit, left with a suspense question which created this much hype that ppl are crazy to watch this film. Has any new film, regional film without known star of south has created havoc like bahubali 2? Not even Bahubali 1 could do that, this is euphoria created based on part 1, After theatrical release, Tv Screenings, Curiousity was build up, now they came in april, a open field when no big hindi Film is here to compete, like Part 1 was clashing with Bajrangi Bhaijaan.
If Bahubali 2 would have come on Eid with Tubelight & Made 41 Cr, that would have big blow to mighty khan.
Bahubali 2 is Exceptional work, comes once in a while, can't be repeated.
