That's exactly what I'm saying
I used to have no trouble at all getting up to 155-65 really quickly and staying there. Now, just a few weeks later, I'm having to run faster and harder and with an incline to stay at that level. One of the things I love about my HRM is that I can really, tangibly see the improvement in my fitness, even in the month I've owned the F4. It's really cool.
Also, if you use a treadmill or other cardio machine at the gym, you might enjoy my new favorite thing--the Heart Rate Control setting. You set your target heart rate (I choose 155, which is right at 80% for me) and then the machine adjusts the speed and incline to adapt to your heart rate and keep you at the right level. I've been doing this for about 2 weeks now and I love it because a. I don't have to be messing with the speed and incline myself while I'm trying to run, and b. I can see that I'm having to run much faster to stay in my zone than I did just last week. It's great.
