+1 to use 'table' instead of 'tbl'.

But, I was thinking about different naming convention. Since the
proposal will already change the member, then this is probably my last
chance to propose this slighty different approach, so I'm just putting
it out there to see what people think.

Background -- there are the following counters:
1x "apply" error counter
2x "synchronization" error counters
7x "conflict" error counters

IMO it would be better for the "synchronization" error counters to
have a common "sync_" prefix; this is consistent with all the
"conflict" counters having a "confl_" prefix.

e.g.

CURRENT
seq_sync_error_count
sync_error_count

MY SUGGESTION
sync_seq_error_count
sync_table_error_count

~~

Thoughts?
