In your scheme, 1.5s & 2.5s will still be uncertain (as they are now). And there are enough autistics where those will occur.Then what about intermediate option. Like you can have
ASD 1- roughly ASD 0.7
ASD 1 (self explanatory)
ASD 1+ roughly ASD 1.3
ASD 2- roughly ASD 1.7
ASD 2 (self explanatory)
ASD 2+ roughly ASD 2.3
ASD 3- roughly ASD 2.7
ASD 3 (self explanatory)
ASD 3+ roughly ASD 3.3
(BTW, ASD0.5 is known as Half-Aspergers...
