[My 2 cents]

According to the specs that they sent me, they want a 4" pole sunk 5' deep for one utility. There's no way for them to know how deep you went (5' is just crazy) but they will certainly see the pole diameter. The good news is that the office people you talked to were probably in Honolulu and don't have a clue, and the installers, at least the ones I dealt with, were very helpful and understanding. Up to you how you want to proceed. Good luck.
