If you can find the deepest platform below sea level I'll be very
impressed (not counting our discussion here last month).

The answer was in the link on the post that you replied to, kind of proving
my point ....

That's very odd. As recently as last month when this discussion was last
held, the deepest point (below sea level) was quoted as being on the
northern line a little south of Waterloo; I wonder why the tfl site
never got quoted (rather than several others).

The figure of 105ft below sea level is a little suspect, as the
published drop for their lifts is 100ft, and ground level is about 35ft
above sea level. Oh well.
