| Hi Chris,
Thibaud's positive/negatives are single notes sounded (in every register) as FFF/ppp -- an explosive timpani-like attack, followed by a long pianissimo fermata. Hard to control at first and very good for the aperture.
Jim knew Pierre rather well. Didn't he mention them?
The more important point that I hope that I made is to practice articulation exercises (Gekker, Arban, etc.) and flexibilities (Bai Lin, Arons, etc.) in pp from time to time. Many only apply the principle to Clarke and other flow studies. . .
Best,
