That orpha= n rate increase will go to whoever is producing the 20MB blocks, NOT you.

This depends = on how miners are connected.

E.g. suppose there ar= e three miners, A and B have fast connectivity between then, and C has a sl= ow network.
Suppose that A miners a block and B receives it in 1 = second. C receives it in 6 seconds.
This means that blocks mined = by C during these ~5 seconds will be orphaned because B gets A's block = first.

Yes, if you = are on a slow network then you are at a (slight) disadvantage. So?

There are lots of equations that go into the "is mini= ng profitable" equation: cost of power, Internet cost and connectivity= , cost of capital, access to technology other miners don't have, inexpe= nsive labor or rent, inexpensive cooling, ability to use waste heat...
