Yeah that makes sense. Here's the justification for the Rich Hill chart, which seems to be the most reflective of the actual trades made since 2012...
Teams don’t make their charts public, but Rich Hill of PatsPulpit.com tracked every pick-for-pick trade that has been made in the NFL since the adoption of the new rookie wage scale in 2012 and used those trades to put together a new chart that shows how teams value picks under the new system.
Apparently teams have updated their charts once more to reflect the rules allowing the trading of compensatory picks.
