Right out of the CT playbook: When busted, make random demands. "Could you make that 96dpi?" "I don't like the background color." "Why not lovely pink?" "I don't trust your fancy software." "Who needs math?" "Trust me when I tell you he's right alongside JFK" "All my friends agree with with me, so why can't you?"

Who's been "busted"???

You have. On your silly speculation that Chaney is right alongside JFK in Altgens. Remember? It is, after all, the reason why you're so desperately trying to derail the conversation.

Tell us Mark - why can't you simply admit the truth? JPG is a lossy format, and I understand that you didn't know that, but you've been schooled, and it's time to give up your claim that you can measure to the pixel on a format that simply doesn't have the data.

Amazing. Yes, of course, JPEG is a lossy format, but atomic clock precision is hardly required here. It's doesn't really matter that much whether you estimate Hargis to be 20% or 25% or 30% farther away than Chaney. It's still significantly more than suggested by the difference in windshield width.

Let me remind you that your original claim was this:

Quote:You cannot do pixel counts on JPEG's...

But you can do pixel counts on JPEGs. You can always do pixel counts on raster graphics. Results may vary, of course, depending on compression method and level. The question is whether the deviations are significant and relevant. In this case, they aren't. You're just blowing smoke because you've realized that the math is against you.
