Make sure you have all of your information correct. On the watch, go to settings, user settings, and put in all the information- sex, height, weight and age.
Also, make sure that the chest strap is on securely. If it loses contact with your skin, it can impact the reading.
I have an FT7 as well, and it is pretty accurate. Keep in mind that the HRM is with you the whole trip- from warm up to cool down, and takes those times of lower heart rate into account.
The last suggestion I have is, you might want to check the battery if this does not seem to help. Even if it is new, it might still need a battery, and low batteries can impact the accuracy.
There are no elevators in the house of success.
