But seriously though, it’s a fitness “tool”, like a scale for measuring weight and body fat %. It’s not “law” or gospel (thankfully). Do not live and die by it, rather use it as a guide.

I have the Polar m400 GPS w/heart rate monitor, and it’s amazing. I got turned onto it by fellow Football (Soccer) Match Officials and based on what I know about myself, it’s pretty spot on, and came in at a reasonable price: bought, opened, but never used, off of eBay for around $180 CDN.
