There is a perfectly valid explanation for why you see the prefix method as winning, and it has nothing to do with the order of blocks, which is shuffled at random before every simulation.

But because you are not bothering to actually read or understand what we're trying to transmit to you, because you're too busy "lol"-ing and accusing everyone of being in complete error, here it is:

Both methods traverse the same blocks in the same order

Now, I won't even attempt to bother to explain the consequences of this. You would just skip through, and the other guys don't really need the explanation anyway, if they just think a little.

For you, it's called "same conditions". For us, this is exactly the reason the prefix one wins more, but when it loses, it loses in a big style.

It also has to do a lot with the way you chose your parameters, for the number of blocks and so on.

Maybe go ask your beloved AI what's going on there.
