5 is easier than 4 for me. Decent time on the 3x3 though, fastest i've done is 1.27. It's ridiculous that the record is about 3 seconds.
Dunno what cube you're using for the 3x3,but it's worth getting the speed cube if you haven't got it already, it turns much faster than the standard cube: https://www.amazon.co.uk/dp/B07FMVFQS8/?tag=not606-21
Ah ok, i'm using a bog standard one I assume, it's not got neon colours like that anyway. Can't see it shaving 27 seconds off let alone 1 min 25 but might give one a go.
