Do a ride tomorrow, see how we go hey?

Testing for that isn't easy if you aren't doing 40km TTs
As far as the tool being a joke, what could you possibly be basing that on? Every single experienced power meter user that has bothered to do the data and do a review on it seems to be very positive about it. If you can afford a SRM then good on you. Many of us cannot, and if you use it wisely then it has potential to be extremely valuable. I'm not expecting it to be useful for pacing 2 minute efforts but more for TSS values and decoupling, which are helpful for gauging your progress in periodisation. I'm nursing a bung knee from overdoing it.

I agree with Vander - there is only a slight relationship between HR and power, and only for longer efforts. Wired PT hub kits were under $750US before they discontinued them last year.

No - I don't. Having run power analysis over my data files in the past, no two rides ever came up with the same relationship between HR and power. And that was just for my data, let alone trying to come up with an 'average' based on 'average' riders. My estimated FTP power is up 30W in two years, but my FTP HR is down by ~ 5 BPM. How would the Powercal account for that? The Powercal is a simply a toy.

But note Alex's comment in this thread about DCRainmaker's review - 3rd comment on page one. There is a fundamental issue with the Powercal, therefore it is a power estimator only at best!
Note the price of new powermeters have come down a long way - Quarq's, Power2Max and even SRM's! And if you are willing to buy used can find wired SRM's under $500! Note I have bought mine all used and all work flawlessly…
