Does the timing end when the Loading Screen that appears before full ending appears or right after it? (For example going up with elevator at Crash 2 triggers loading screen before ending)

Does all relics in Crash 2 also add 2% like in Crash 1? And Crash 1 have 102% if you have at least gold relics http://prntscr.com/fq7xie

I have question, what is better in New Game+, running shoes or neutral slide jump?
