I don't believe there is such a thing as a "late variable" per accepted AWHONN and ACOG nomenclature. There are early, late and variable decels, and there is no significance to categorizing a decel as "variable with late component".
By definition, a variable decel really isn't subtle. It happens suddenly and I believe more than 15bpm drop. That wouldn't be sudden.
You have been asking a lot of questions about how to categorize and recognize decels. I would strongly recommend AWHONN's fetal monitoring courses.
