I don't use a Beatmap; I don't use any click track. Any time I count off, it's just in my heart. Sometimes I'll go off the feel of a crowd, like if they way they're bouncing is a little quicker than the song, I might kick up the tempo a little bit. I see where the crowd is at. It's nothing drastic, but all the tempos are from my internal clock.
My advice always is to start very simple and master your timing and master the most simple beats that you can, and you just keep elevating from that. Trying to go right into playing fast is not necessarily the best way to go about it, because if you don't have your foundation locked in, it's hard to progress.
