Tell you what Tom, when FET comes up with a daylight calculator that is as least as accurate as the RET daylight calculator, then you can declare victory.
No dumbshoe. You need to provide positive evidence for your claims. If you claim that the calculator is accurate you need to demonstrate that your claims.
Your phrase "when FET comes up with a daylight calculator that is at least as accurate..." assumes that the calculator is accurate. This has not been demonstrated. You have provided no real world observations and no evidence to show that it is accurate.
As for real world observations... Well, I've proposed that FES members perform real world observations on the days of the equinox, but there were not very many takers.
It's your burden to provide evidence for you claims. We have not made any claims about daylight times here. You have. You posted a map and claimed that it was accurate. You need to provide evidence to show that it is. You're the claimant. We're the skeptics.
"Prove that ghosts don't exist" is not a valid rebuttal.
"Prove that it *didn't* happen" is not a valid rebuttal.
You're the claimant. You're making specific positive claims. You need to provide evidence for those claims.
Provide evidence or shoo.
