Every point surely got 3 wires of LNE...

If the point is looped to another point then you see extra wires.

Why you want to have direct from DB for all 8 points?
TV appliances won't consumer a lot of electricity, needless to have single direct point from DB.

Looping will save you a lot of wire and tedious work for the wireman, as well as cost.

Whether to consider direct or loop is about the electricity consumption of particular point.

Looping won't cause reliability or performance, as long as it is not over-used, or over the rated power/current of the wire.

If every point got direct wire, you see tons of wire being pulled over your place.

The important is to ensure power hungry point/equipment is not using looping method, but direct from DB, eg, heater or those need to use more than 8~10A one.

By switching off the individual circuit breaker normally like 10A/15A20A at the DB will roughly know which point being shared/looped around.
