Yes, the ratio is calculated like this,
{code:java}
statsTable.localReadWriteRatio = statsTable.localWriteCount > 0 ?
statsTable.localReadCount / (double) statsTable.localWriteCount : 0;
{code}
Since it is already present, maybe you can update the ticket.

> Nodetool tabestats reports the space used live and total per table, but not
> for the entire keyspace. This would be useful information.
> Also, in the table level stats, it would be useful to have the read/write
> ratio. This metric is important in choosing compaction strategies such as
> LCS.
