Technically yes.
Provided that my math is correct..For a 1" thick piece of Moretti glass the maximum(fastest) slow cooling rate (annealing through strain) is 3.74 degrees F/min or 224 degreesF/hour....

I also skip the strain soak in lieu of a very slow ramp down. (about 50-60 DPH).
As long as the temp changes are slow enough between annealing and strain point then you won't "un-do" the annealing...

Hold time is proportionate to the thickest part of any given piece. Since overannealing is NOT an issue it's best to err on the side of caution with both the annealing temp and soak time.
968F is...
