In reply to MischaHY:
The way in which teach novices to build multi-pitch anchors in sport-style climbs in the Netherlands is based on the guidelines formulated by the German and Austrian alpine-clubs.
- Anchors on solid bolts are not equalized, but one bolt acts as a powerpoint, while the second bolt is used as a backup.
The exact way in which we instruct novices on sport anchors at our alpine club is pictured on page 16 in the centre panel:

- Note that the sling is attached to the carabiner in the backup bolt via a clove hitch (adjustable according the circumstances) and that the end of the sling is clipped into the carabiner (to prevent anchor failure in case of the clove hitch slipping under high loads).
This is also how I learned sport-anchor building from an Austrian mountain guide during an alpine rock climbing course.
No need for a cordelette, just a 120cm sling with a bowline on a bight.
