Well spotted, thanks.

and some posher laminates a slightly more than that (although most are
less to be fair).

Mine is 10mm. I'm wondering now if a thicker product might not have
given rise to the problem, though it's a bit late to think about that.

When you have a void under a join in the board, you end up with the full
weight of the person standing on it being supported on a third of the
thickness of the board (i.e. the bottom part of the groove, or the
tongue), so its quite easy to break something - especially as most are
MDF backed and that is quite weak in tension across its layers)
