Flourish heal information

I know this may be difficult but it would be helpful to see the amount of healing attributable to Resto Druid’s Flourish.
Here’s the spell (talent): http://www.wowhead.com/spell=197721/flourish

It doesn’t provide a “buff” just extends the duration of hots and then rolls to CD. So it doesn’t show under buffs nor does any of its healing (6 sec on all hots) show up under flourish (I’m assuming it remains with the hot itself).

The only way to get any information is casts and then it is just raw count not how many hots you had rolling when you used it or the value of the extra 6 sec of heals. In determining proper usage and talent choices this information would be very useful.
