It doesn't matter. The %MHR zones are only estimates. What they try to estimate are point of maximum fat burning, LT, and red zone. The actual percentage doesn't matter, the target HR number is what's important.
Still, you're not going to ruin anything by going 2-3 beats above your aerobic zone. In fact, my intuition tells me that you'll actually gain a bit more if you get enough rest.
If you're really burning to know then spend the $85 for the test. I did.
