Too much pressure can cost much energy if you ride over coarse gravel and bounce around instead of gliding over small stones without feeling every 1cm small stone.
If you ride on smooth tarmac, narrow width and high pressure is a good point to start and adjusting pressure according to the weather conditions and soreness of the butt.
