Absolutely. It seems that Weir has seen my demonstrations.... and that Ainslie hasn't. You may note in my last video that I also can reproduce the high-amplitude oscillations in Q1 that happen when ramping up the FG. I didn't emphasize this at the time but I can demonstrate it specifically, on demand, and it won't take me four hours to do it either.

But look.... I guess you only get 4 hours of "hangout", it just went down ... and just when it was _finally_ getting interesting too.

Listen to her flailing about. She doesn't even have her paper in front of her to see what she claimed! And now she's trying as hard as possible to divert attention from the FACT that they could not reproduce Figure 3 without moving the probe or otherwise tricking the circuit. Heat or not.... no Figure 3 means NO VALID DATA OR CLAIMS IN THE PAPERS and they must be retracted, errata issued, and apologies made.

But am I going to hold my breath waiting? No. She will never admit to what she has just demonstrated live on camera.

Figure 6 Gate drive is under 10 volts. I make it to be about the same as the 8.5 or so that they were so happy about.

Not sure who the new voice was, but at 3:48 or so he had them adjust for +12 at the Q1 gate and perform a capture with the CSR showing Q1 passing current and then had them make another capture with the CSR probe moved to te wrong side of the CSR, which made a pretty good replication of FIG3.  It is hard to tell from the video, but even with the CSR probe on the wrong side, it looks as though a bit of current flow continues to be indicated (which would be the Vdrop across the wiring resistance).

They then began discussing FIG6.  In FIG6, during the Q1 on time, there is a very small amount of current being indicated.  This would be consistent with having the probe on the wrong side of the CSR, as the "CSR" would now actually be the wiring resistance between the batt- side of the CSR and the ground point used as the reference for all the probe grounds, which would be much less than the 0R25 of the CSR.

Note that in FIG3, there does not appear to be the slightest hint of Q1 current.

And then the feed went down again...

Are they actually doing scope internal screencaptures, or is somebody just taking a still photo of the screens with a cellphone or something? I didn't see any fingers near scope buttons when the "snaps" were supposed to be taken.
