Read the question on the I-129(h). It specifically directs you to include "only those periods in which the alien and/or family members were actually in the U.S. in an H classification." It's hard to be "in the U.S. in an H classification" without ever entering the United States.

You can't learn anything from this question. For example, If during the last 6 years you were on L1 (This is not H, right ?), this period also counts toward the 6 year limit.
However, I have heard of people who got more days by deducting their time outside the US. So if the rules didn't change, you may be able to change this decision.
