A clearing delay you mentioned in another post was actually an issue with
CM8000. But it was solved in the final patch (TK 3.12d). More importantly, it
was a problem only with large TT *and* extremely fast time conrols.

And then there is hardware issues, causing random access to slow down with
increasing access range. That's highly dependant of the hardware, so I'm not
going to even try to make a statement about it. Except that I'm convinced it is
about a few percent at the very most.

But both issues do not apply here.
And I'll have to agree with you that some bug is pretty unlikely. :-)

Be happy (because then you will be happy)!
