Not trying to start an argument here, but promoting the psychology of 'viewing' a root before actually planting it is beyond my understanding. Why not just plant a seed in a prepared medium to start a plant therefore avoiding any possible damage to the most delicate parts of a sprout...... Just planting a seed has been the only way I've done it for over 2 decades and with 99% success, I've not found any reason to punish a seed otherwise.
A good medium, 1/4 inch planting depth, moisture and warmth will skip all the rocket science.
Having managed a 'legal' seed business for years and raised in a farming community, our methods of just planting any seeds were far more successful than any other.
Guess some just have to try to re-invent things that aren't broke.
