Yeah, absolutely. In fact, here's something for y'all to try. Read this aloud at a normal pace:

one-one-thousand
one-one-thousand
one-one-thousand
one-one-thousand
one-one-thousand
one-one-thousand
one-one-thousand
one-one-thousand
one-one-thousand
one-one-thousand

Now, subtract from the time it took you to say all that the time it would take you say 'one-one' at the same pace. That's how much difference PAL speedup makes. Approximately.

I find the NTSC judder more noticeable, and I must point out I don't notice that at all, either... unless I'm really, consciously watching for it, in other words not really immersed in the viewing experience anyway. It's kinda like saying, 'That orgasm was 0.41 seconds shorter than my last one.' Well, frankly, it must've been a lousy orgasm.
