Timing in Ecuflash Vs Logged timing.

I actually had a timing anomaly last night. It would log 400load but it clearly using the 360load column. I had 1byte load set to 2.0 as well as evoscan. I was slowly bringing boost up, hence the need for a 2.0 1byte setting at the time. All timing trims were set to zero during tuning too.

I have a question.
a value of 5 in the hi octane ignition table represents spark is being fired 5 degree BTDC ?
a value of 0 in the same table represents ?
a value of -10 in the same table represents ?
or +ve is just taken as advance and -ve is just taken as retarded timing ?

The spark plug firing ATDC is not possible because it takes a little bit of time for the air fuel mixture to burn, so if you fire the spark plug ATDC the piston is already going down , most of the energy will be lost + knock too.
Some one can clear this out ?

Uh...the spark can fire as long as there is unburned mixture in the cylinder. Position of the piston is irrelevant. Firing ATDC is not efficient, but it happens all the same. Not to mention that the map can't run in one manner, then randomly switch function as it crosses certain cells.
