Datalog terminology questioins

Hi folks. I've been working on improving my cold starting through analyzing datalogs and have a couple of questions for clarity:
1. What is the definitioin of a "cycle" and what period of time is this? For example, if I set my after start enrichment for 300 cycles, how long will this last in seconds such that I can track it in the datalogs?
2. In the datalog, are the values for afterstart enrichment and Warmup Wizard cumulative? The columns Gwarm and Gammae look to be cumulative, but I'm not positive.
3. In the datalog, what is the column titled "engine" capturing? Most of the time mine just stays pegged at "1" but sometimes shortly after start up it will spike a bit. What information is this capturing?

1. One cycle = 2 crankshaft revolutions on a 4 stroke motor.
2. Yes.
3. It's a bit by bit status of the engine.
