I meant that if you would buy 700.- Euro worth of SAF, you'd get around 70 xp.
If you would pay for Extra, you would need to fly at least 350XP worth of flights to get that same 70 XP extra (simply did 350*0.2).

My point in that was that if you'd want to speed up requalifying, it would seem that flying less but adding SAF might be more interesting than the 20% extra xp when needing to requalify.
Let's say the goal is 300xp.
300/120*100= 250 (+ 50 xp bonus)
Alternatively when buying SAF, you only need 230XP (+70 xp via SAF).

I do agree that this is by far the most interesting aspect of the deal, Especially when you know you'll be flying enough regardless or are aiming for Ultimate, but it is not necessarily as interesting if the goal is Platinum or lower.
Am weary of the promos, and even more so as to what it means to the current promos

Just would have hoped that Extra would be something that would be genuinely interesting for most types of customers. E.g. different 'packages' for Explorer, Silver, Gold/Plat or an evolution of the abonnements which AF has.
Lounge access on arrival would be more interesting for Gold/Plat, whereas lounge access in general is a tangible benefit for explorer/silver.
Upgrade vouchers for Plat, free normal seat selection for explorer etc.
Low season fares/jokers for award flights etc (although that would be nice to have more with status)
