number of rows in EXPLAIN for unpacked vs packed tables

[C.R.Vegelin]

Hi All,

I compressed a MyISAM table successfully with MYISAMPACK, followed by MYISAMCHK.
Both tables (MyISAM + Compressed ) have exactly the same number of rows with Count(*).
But when I give a SELECT query with EXPLAIN on both tables, I get different number of
rows.
For example: EXPLAIN SELECT ... FROM data ... shows 1983 rows,
but the same EXPLAIN SELECT ... FROM pack ... shows 2064 rows.
Any idea why ?
