First of all, if you are going to try to help someone out, maybe you should be sure your information is correct and the source reliable. Your quoted source doesn't really fall into that category, neither does your information.
Pyramidair sells Beeman products and that blog is pretty much recognized as a shill for Pyramidair. Beeman is an airgun expert only as much as he sold tons of them and wrote a some self serving books on them. His Bluebook of Airguns was a prime example. A self described leading collector writing a price guide that inflated the value of the pieces in his collection and devalued those that aren't. Other than that he was a pitchman, nothing more, who recognized what sort of airguns American consumers wanted and sold them by the thousands.
Beeman only recommended that kind of hold after the rest of the airgun world had already discovered it. The artillery hold applies to all spring powered guns, not just high powered models. They all work the same, some are just more powerful than others. Power levels don't change how a spring gun shoots, they all have the same recoil movements. Some respond differently than others, thats called hold sensitivity- in other words, some require the shooter to be very consistant with hold to be accurate, some don't.
All of the vibration occurs during the firing cycle. The spring powers the gun, and it has everything to do with the firing cycle. It vibrates when it is released, moreso if the guides are poorly fitted. However, that vibration is more annoying then detrimental. What needs to be controlled is the recoil. Spring guns have a unique double recoil, both rearward and forward as the spring drives the piston to the end of the compression chamber then rebounds at the end if its travel. This action is why it takes practice to shoot any spring gun with consistant accuracy, and high power guns are more difficult to shoot accurately.
The R1 hardly started the magnum airgun rolling, rather it came about some years after the power race began. Beeman saw that the high powered guns such as those made by FWB and BSF were selling well, so he went to Weihrauch and had the HW35 modified with a longer compression tube and named it the R1, HW80 in HW terms. It was the most powerful airgun of its time, but hardly the first high power air rifle.
As for the rest of your response, if you feel that this place is full of pompous twits, why do you visit here?
