Cranking speed not consistant

Sometimes when I carnk my car it turns over faster than other times, any suggestions? I worked at this before and I replaced the starter, new alt. Cleaned terminals amd grounds and bought a bigger better battery. Before the crank speed was really slow and would cause the car to flood. I do not have that issue anymore but the crank speed is inconsistant. I haven't really worried about it, was just trying to see if anybody had any suggestions. The car always crank starts and runs no matter what, I can turn it on turn right back off short trips long trips it does not matter.

I also removed an aftermarket alarm that had a relay wired in to the ignition, that is what made the biggest difference.
any suggestions would be great.

Measure voltage at the starter while a friend cranks for you, if you see low voltage you either have a connection or battery problem. You can also try to touch one probe directly to the battery post (not terminal), and the other to the positive stud on the starter. Measure both while cranking and not. You shouldn't see a significant amount of voltage drop across the cable. If you do, there's a dirty or damaged connection. You can do the same with the ground. If all that checks out, then it could be high internal battery resistance that's dropping the voltage.
Edit: Sorry I missed that you bought a new battery already. Could still be a cable problem. I've seen battery cables corrode 2 feet away from the terminal, inside the insulation before.
