I had a look and saw that there's Baerwald, Loefgren B and Stevenson A to choose from. Loefgren was the first in 1938 to develop a solution for this problem, followed by Baerwald 1941, Bauer 1945, Seagrave 1956, Stevenson 1966. Graeme Dennes analysed the various solutions in 1983 and found that they are mathematicall identical to those of Loefgren.:http://www.vinylengine.com/phpBB2/viewtopic.php?t=4854
see in particular e-pages 7, 8.
Give credit where credit is due! Baerwald's solution is identical to Loefgren's A-solution. Clearly, in view of these (historical and mathematical) facts, credit should be given to Loefgren, and to Loefgren alone, not Baerwald, and it should read "Loefgren A" / "Loefgren B" instead of "Baerwald" / "Loefgren B".
On a sideline, the only manufacturers that make that (incorrect) distinction (Baerwald, Loefgren) on their websites are Wally Malewicz and Judy Spotheim (La Luce turntable). I have contacted both asking to set the record straight in view of the facts. As you can see, neither has modified the site accordingly: http://www.simplyblack.net/WVC/index_wally.html
