well wouldn't it add up?

someWhatRandom1 xor someWhatRandom2 xor notRandom3 xor ...

should be more 'random' than just 'someWhatRandom1'

XOR is the worst hashing function imaginable, especially if the data isn't truly random, because it can cancel out to become even less random!

It's better to use a KDF or something. Even a block cipher should work far better than XOR.

i'm not sure it would necessarily be more random if you're mixing in a lower-entropy source which the accelerometer probably is
