It has 5 tables

Valve Clearance Limit - Cam advance vs VVEL timing map
VVEL A - RPM vs VVEL timing map
VVEL B - RPM vs VVEL timing map
VVEL C - RPM vs VVEL timing map
VVEL D - ??? vs VVEL timing map
VVEL Intake Phasing - VVEL timing vs Cam advance map

From one of the post on the forum, Valve Clearance Limit table is a safety feature to keep the valves away from piston.. other than that I cannot find any more information

Does anyone have a breakdown on the purpose of the 5 tables?
Some discussion on the VVEL maps here: ECU ; stock ECU Vs Nismo ECU difference
