P.S. I am sure you already have noticed the last note in the QRH just before the table. Max speed (from table) might be higher than VFE (displayed on PFD). In that case you may follow VFE.
In my QRH that last note refers to VLS not VFE - VLS is displayed on PFD and always valid for the
actual flap/slat conf. Do you have a different QRH?
I said you guys were making it complex... I cannot tell from your profiles if you are A320 rated. The QRH refers to the
displayed VFE next for configuring. It is always safe, you won't break the aircraft, you do not need to work out an "actual" VFE next as defined by MB2002.
On a clean-up for diversion you already know the VMAX in the landing config, so you can accelerate, select Flap 1, check/work out your new VMAX, accelerate and select Flap 0 passing VMAX-10 .. all done in slow time using SEL SPD.
It is far more important to maintain SA than to bury your head in the table more than necessary.
