Typebar's illustrating picture is not suited to the evidence for David's statements on two points.

This picture is front-strike machine's and staged event 'cause of too much tangles. Jamming typebars' picture should be on up-strike-machine's and during actual operation. It's because this picture should illustrate David's statements. The type-writing machine at prototype era, it should have up-strike mechanism. --Raycy (talk) 17:07, 10 September 2009 (UTC)[reply]
David wrote new doc that is David(2000)[1], and I haven't read though. It should be checked because his "jamming problems led to QWERTY" theory was on suspicion for a while.--Raycy (talk) 18:15, 10 September 2009 (UTC)[reply]
Associate Professor Koichi Yasuoka[2] points out two facts that should be proven ,

1. The existence of the nuisance of type-bar collisions [3]
2. Strong regulation between keys' layout and type-bars' arrangement [4]

,during the prototype-machine era.--Raycy (talk) 18:40, 10 September 2009 (UTC)[reply]
Yasuoka also says up-strike machine's type-bar should never been called as 'arm'. I gess it might be called as 'arm'.--Raycy (talk) 18:40, 10 September 2009 (UTC)[reply]
