The code contains too many data contigus levels

Why you should care

When creating a new data level, do not add 1 to the previous level. Having not contigus level is easier for inserting an intermediate level later, if needed.

How we detect

CAST Highlight counts one occurrence each time two contiguus levels are detected.
