You were told from the off . It seems you don't understand simple english any more than the subject .
Here it is again .
I have explained to others who asked here and elsewhere and will do again ,but can't be arsed doing it for you .
There are also multiple methods throughout the web and literature . It is hardly difficult or a secret .
You may have heard of Thom but possibly not read or understood him ,that is an obvious starting point .
All methods when done properly produce the goods .
There are countless examples of "on site observations " that are demonstrably wrong , I mentioned one from Bryn Cellu Ddu in the previous post and the literature is replete with them .
If you are incapbale of undrerstanding the uses of the formulae and how the results derived can be shown to be in error and can't understands how Michell's suggestion of the bearing in TOSOLE is wrong , or even how to calculate an alt , then that's your problem .

What I will gladly do for you ,is take a bet ,you suggest a site and I will tell you where the sun will rise or set as seen from the site or the alt ,to the same tolerance as is usually expected from astro calc. A referee can hold the £100 and check the test .
Lets see if you can put your money where your mouth is ,or willing to accept real tests .
