I play 60 - 100 % realism, mostly depending on the time I have left for playing SH3.
During the week it's around 60%, on weekend it's usually near 100%.
As long as YOU are happy with your level of realism, then why change?
If you're getting bored, then YOU are free to change either the realism setting or the game you're playing.
The only time when realism level really matters is when someone is giving advice here on the forum. Maybe his advice isn't that usefull for you, because he has a lower realism setting OR modified some data of the game.
It would be nice to remember this when you are posting, in order to NOT confuse too many other subsimmers here on the forum.
This is no personal attack, but it really took me some time to find out why Mr. Mohr actually COULD pass through Gibraltar or the English channel on SURFACE.
I find this very confusing sometimes.
Just my two cents.

OK, really funny, who gave me that 'Bangkok' avatar?
