Onsights up to four grades harder than redpoint

Climbstat has based on the 8a database published an interesting graph showing how much harder it is to onsight compared to redpoint. The analysis goes in hand with the 8a system giving three grades minus fives to the onsight ascents. It should, however, been mentioned that we plan to increase the onsight bonus with ten points possibly encouraging climbers to focus more on onsights rather than redpointing. "This indicates that an onsight becomes harder the harder you climb. The average onsight maximum is 2-3 grades lower for climbers who climb up to 7a or 5.11d redpoint but it increases to almost 4 grades for climbers with a maximum grade of 8a or 5.13b (and still widens further)."
