Yeah I'd say for those caps 4-5 would be a good start.
If you have problems with the fishyness then spreading out will definitely help, but I haven't heard anything about other advantages to spreading out the dose.
Maybe someone else can chime in about that.
I take it all in one hit coz in liquid form it tastes a bit nasty. When I was using caps I tried spreading out the dosage and taking them all at once, but didn't notice a difference.
