I know... the thread was slow all day, I was wondering why posts were so slow up to the 5K... then bang - he stole it!!
If I notice that a milestone is approaching, I usually back off and let someone else take it.

It's like waiting until a noisy train or plane passes by, in order to resume your normal conversation.
If anything is ever considered normal here.
