The setups sheets from some our drivers still have the mistakes in the top deck setting indication.
So I have to explain again the main ideas of red dots in the flex settings of our setup sheet ( both for top deck and lower deck also):
#1. The red dot indicates that this point is fixed against any shifting ( lateral and longitudinal). You can provide it by screw or by AT21/AT21S/ST24 ball stud.
#2. ST09 under outer (side) screws/AT21/AT21S/ST24 on the top deck prevents the fixing of this point of top deck and it should be indicated without a red dot according to #1.
(This is due to ST09 are higher than top deck thickness and these outer holes are bigger than ST09 diameter).
#3. ST09 under the central screw on the top deck doesn't prevent the fixing of this central point against the lateral and longitudinal shifting as the central hole has exactly the same diameter as ST09.
So this point should be with red dot even with ST09 installed into this hole (according to #1).
