Are my autovacuum settings too aggressive for this table?

Hello list,

I am sure this question has come up before, I have scoured the documentation and I think I have a good grasp on the
autovacuum. I wanted to ask the team if my settings for this particular table are too aggressive, I have the following
setwhich is producing a vacuum analyze multiple times a day. 

I think the defaults out of the box were not aggressive enough, so I went with the following on the global level, I
willpossibly move to table level if needed.  I tried to show the stats below of a 10 minute interval during peak time.
Anypush in the right direction is appreciated, I want my tables analyzed and vacuumed but do not want to over do it.
Therest of the autovacuum settings are default. 

I know the stats are estimates so here is my calculations.

Live tuples = 19,766,480
Analyze scale factor = 0.001
Analyze thresh = 5000
Thresh + live_tuples * factor = 24,766

So an autovacuum analyze should trigger around 24K tuples modified, is this to little or too much? Same goes for
autvacuumvacuum, is it too aggressive?

autovacuum_naptime = 1h
autovacuum_vacuum_threshold = 10000
autovacuum_analyze_threshold = 5000
autovacuum_vacuum_scale_factor = 0.002
autovacuum_analyze_scale_factor = 0.001
