INTERESTING, BUT "SHREE GARUDA-PURANAM" MENTIONS TRIPUSHKARA-YOGA AS AN EXTREMELY MALICIOUS.
I am not very much interested in Jyotish (Jyotish rules don't work for prapannas of Bhagavan Shree Narayana, that is for Shree Ramanuja-Sampradaya, as we are free from all the fetters of karma, including prarabdha - so for us Jyotish is just a useless Vedanga), but Internet (which is of course is very far from being trustworthy) tells that Tripushkara-Yoga is auspicious.
I have found "Tripushkara-yoga-auspicious"-opinion both on Hindi and Russian Jyotish sites and popular Internet-belief is that "good deeds made on the day of Tripushkara-Yoga give a thrice benefit, while bad deed results into multiplied-by-3-bad-karma".
Anyway, as usually I don't believe to the Internet-opinion. Praman from "Shree Garuda-Purana" (Chapter 127 about Ekadashi-Vratas) tells that Tripushkara-Yoga is just very, very malicious (with no aspicious phalas at all):
