The 300 is capable of a slightly steeper descent in some of those configurations at least. I just want to know the descent angles for the mentioned configurations.
If somebody knows the numbers for just the 700 or just the 300 I would be happy with them as well.

Just in order to know what extreme to go to when you are kept high on arrival.

Think a lot will depend on whether you are discussing 300w vs 700w, or 300 vs 700w.

Don't think number crunching will answer your Q.

For sure the 700 will be harder to get down, & ++++ if you are discussing in comparison to a non-wingleted (new word I invented? ) 300.

Don't think you can solve this with numbers, fly it & see.

I have just gone from 800 to 800 Short Field Perf, that is a "big" difference, no Full Ext till F30, Bugger ! they killed my best Intermediate App friend. . . F10

captplaystation,
300 vs 700w

Regarding the 800 SFP:
Can you still maintain around 4.5-5 degree with idle Gear + F15. Even without the Slats fully extended.

So do you remember the F10 numbers:

200 Flaps 10
170 Flaps 10
