You will find that given the choice between a sector two and a sector three entry, ie. within 5 degrees zone of flex
based on heading (and remember no zone of flex for intersection based holding patterns), you will find a sector two entry will be preferable. Using a sector three entry (because you are already halfway through the outbound turn) will keep you too close to the inbound leg, ie you will most likely find yourself overshooting the inbound turn.
As for intercepting the inbound track, it depends on how far the wind is pushing you and how far from the navaid you are. A 45 degree intercept may be required, but there's no hard and fast rule on this.
