No clue. No, seriously, that would be very hard to estimate.

So it might not be significant at all and we all are just blabbering over something gratuitous 
No, I think the new sort order will be legit very good for people with a backlog (less so for people with no backlog). As for FSRS-5 + <1d scheduling, the effects are fairly small, so don’t expect huge changes.
Btw, Easy Days is coming, and smart fuzz is already implemented.
Is smart fuzz basically the same thing as FSRS Helper’s “Load Balance when rescheduling”?
How can I use smart fuzz
I believe it is different
I know “Load Balance when rescheduling” tries to smooth out the Future Due curve. Is smart fuzz just “Fuzz Factor”, adding a little randomness to the scheduling?
I believe @Expertium is the best person to answer that here. However, I don’t know how I could even enable load balancer. There is “Flatten” from the FSRS helper but it is not the same as Load Balancer.
There’s an option called “Load Balance when rescheduling” which I think I misunderstood. I thought it was doing that while you were reviewing cards, but it only does it when you use the reschedule feature in the add-on. So unless you want to reschedule with the add-on almost every day, then it isn’t that useful.
Also, I would never use “Flatten future due cards.” That seems like a crazy thing to do to your scheduling considering all it does.
Not exactly.
Add-on version: produces greater smoothness, modifies intervals of several cards, requires rescheduling.
Built-in version: not quitse as smooth, modifies the interval of the card you are reviewing, doesn’t require any actions from the user.
Just download the latest beta and it will do everything. No tweaking required, no new settings.
You have much fewer options than I do.

You are looking at Tools → FSRS Helper, DerIshmaelite was looking at the menu that appears when you click the cog icon next to a deck name

Ah so it is already integrated into FSRS 5 as it is. How does it differ from normal fuzz. What is smart about smart fuzz
So suppose a card’s “true” interval (given by FSRS) is 100 days. The fuzz range is [95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105].
Normal fuzz chooses the interval randomly and uniformly, so every interval in that range has the same probability of being chosen.
Smart fuzz makes shorter intervals slightly more likely, bu more importantly, it checks how many due cards you have on each of the future dates corresponding to these intervals, and that affects the probability. For example, if on day 102 you have the lowest number of due cards, then the 102 interval will have the highest probability of being selected.

If you look at the tables generated, it’s a significant change.
It started as a normal Load Balancer but was modified a lot later and have become this almost unexplainable thing without any options that runs behind the scenes.
So, I asked him. He’ll do it tomorrow. For reference, he also proposed this formula:
PSG = (S_forget × (1– R) + S_recall × R) ÷ S
I’m not sure this will work because S_forget × (1 – R) is higher the more you delay the review. I’m only realising this now but maybe putting a minus before this should make the formula better?
(by the way, I didn’t even saw until maybe yesterday that you updated your reply, should’ve just made another reply)
What does PSG mean
Potential Stability Gain. I defined it some days ago.
