Query: Ineffective Mounting

While the shelf itself is as advertised, the proposed mechanism for mounting the shelf to the wall is inexplicable. The shelf came with two 2" wood screws. Here's the list of problems:1. The concept is you sink these wood screws into the wall and hang the shelf on them using keyhole slots. IF I could sink the screws correctly, I suspect I'd never get a good, tight mount to the wall... the shelf would always droop.2. I'd like to sink the wood screws into the studs... but the keyhole slots are 24" apart!3. No drywall anchors were included.I'm not sure if it is easier to rig my own mounting system or just build a similar shelf myself.
