It is a scale for a school or similar enterprise......a scale per their needs will thin slice the learning stages so that the staff can more accurately address the various issues that face surfers at these early stages of development.......once you get to 3.5 you make DBBB's category of "can surf" having just graduated from "can't surf".....so the surfsimply's role is going to be much less influential or needed if at all in a person who can do all the basics but just needs water time and practice to continue to improve.....they focus and their business is on getting raw beginners riding "unbroken" and "green" waves.......they could give two whistles about someone working on more advanced aspects....they don't deal with the "can surf" segment of the surfing population, so their scale that they designed, made and use ends shortly after the "can surf" plateau is achieved.
On the other hand, there must be surf coaches who specialise in coaching up young prodigy competitive surfers.....I would imagine that they would not have any interest in teaching a raw beginner, but only take students on who are already at competition level but want to improve.....I googled randomly and came up with a website from the academy of surfing instructors.....no idea who they are but they have their surf training broken into 10 levels....I took the middle of the three intermediate levels at random and this is what they are:
Level 5 Intermediate Surfer
The participation course is the second stage in learning intermediate surfing skills. Students attend workshop sessions to assist in gaining information and skills at the intermediate level. But, additional practice is required to achieve competency.
Available at ASI Accredited Surf Schools
Participation Certificate Course
Aim Perform cutback & re-entry, and identify types of boards suitable for your ability and conditions.
Prerequisite ASI Intermediate Surfer Level 4 skills and competence
Outcomes
Identify how parts of your board affect performance
Identify the different types of fins and fin systems
Identify surfboard damage
Choose a surfboard for the intermediate surfer based on personal style and the surfing conditions
Identify surfing safety and assistance clothing
Perform and link surfing manoeuvres
Top and bottom turn (forehand & backhand)

Issued ASI Intermediate Surfer Level 5 Participation Certificate
Duration
Attend 8 x learn to surf sessions (2 hrs each).
To become competent at this level will take approximately 250 - 500 hours of additional practice. (complete in your own time or with surfing instructor).
Again it begs the question, why does a surfer need to classify their level? A school or training program must; otherwise how would they know what to teach or how to measure successful achievement? So each school creates their own scale and measures depending on what they teach and specialise in......anyhow, I like the can't surf, can surf, shredder designations if one has to be assigned....then it's just dependent on the venue....for instance, I get asked to join a group going to a break....that day it is 6ft Hawaiian, and the break they are going to is hollow and famous for getting shacked....that's the only reason people hit this spot on a swell.....or the same group goes to the same spot on a day where waves are shoulder to head high and a little fat because the tide is up and swell down....I must have a measure of my ability and what I am able to do and if I can or will join the group or not.....even the rough categorisation of "can surf vs. can't surf" will be dependent on conditions as I could and couldn't the two examples given...being able to sort that goes way beyond even detailed "advanced beginner" or "stage two intermediate" descriptors and is entirely dependent on all variables that can be included.....vs. going to a surf camp and getting a colour coded name tag that corresponds with your "level" and what spot you will surf that day.....a necessary evil but not one needed in my daily life....
I do like the 250-500 hours of additional practice part........at least they are being realistic.....
