2) Spinning it together will increase the odds of hitting better rewards.
This is not true. It doesn't make any difference whether you play 100 spins at the same time or you play 1 spin daily for 100 days.
Take note that every time you play the wheel of fortune, the outcome is determined through some mathematical calculations and they are completely independent from each other.
I think that is right but what is also right is that when you hit 100 spins in an instant of course it gives you a much better pleasure rather than spinning 1 spin each day,there is no mathematical calculation that can take this joy from us

and maybe we get lucky as the more spins the more chances.I know each spin is independent from each other but that false feeling of hope for us mere humans who do not believe that much in mathematics (otherwise I would have been rich and not gambling my money) is great to have and it keeps us going.
