A difference by 4 digits from the last superblock. Bearing the irony that latest superblock could had mined at the peak of 7176 instead 5565 miners with new world records well into the easy 7XX - 8XX digits range (and beyond).
What's wrong with you Riecoin Project??? C'mon, Christmas just around the corner...

It doesn't work exactly like that: the amount of hashing power at the moment of the superblock influences how long does it take to find it, but not how many digits will it have. The quantity of digits (the difficulty) is decided based on the hashing power during the interval prior to the superblock. And since the superblock is in the middle of an interval, its number of digits depends on the number of active miners in the interval of 432 to 144 blocks (expected to be 18hs to 6hs) before the superblock. It's the mining during that 12hs period that defines the superblock's difficulty.
The Riecoin miners demographic at ypool is very much predictable (with 24/7 pattern of single & twin peaks). There's a 24hrs cycle instance that miners seem to rises from 00AM-2AM to 12PM-14PM and then started to decline there onwards; and the cycle repeats (exception for twin-peak over the weekend). As the peak of miners increases (or decreases) for each different cycle so do too the rising and declining rates (for each side of a peak) over the same fixed time period.
If I understood correctly - A superblock could only defines its difficulty based on past interval of hasing power (as connected miners at ypool's demographic) that ranges from 6hrs to 18hrs (2.5mins per block) before and not the future interval (although I'm confused by And since the superblock is in the middle of an interval). At present the superblock event took place around 21PM-22PM of ypool's demographic (at declining side of a peak) that gives at best 8hrs of positive rising rate and 10hrs of negative declining rate with net 2hrs of negative declining rate (for the prior 18hrs difficulty justification), and at worse 6hrs of negative declining rate (for the prior 6hrs difficulty justification).
Now let suppose then 18hrs prior to a superblock event at 14PM justifies the difficulty computation it required from 20PM of the day before (with only 4hrs of negative declining rate before rising again around 12AM that gave at least 12hrs of positive rising rate). And, 6hrs prior to a superblock event at 14PM to justifies the difficulty computation it required from 8AM of the same day (with zero hours of declining rate and at least 12hrs of positive rising rate).
From the surface it's seem illogical to favor a difficulty computed from the declining side of a peak. Since the hashing power at that instance (around 21PM-22PM) is already dwindle down to handle the superblock's difficulty (computed from 6hrs-18hrs hashing power prior). My point being what good is the superblock's difficulty to already declining hashing power at that instance.
How do the superblock difficulty adapts to the amount of hours during either positive and/or negative rate as it required for the 18hrs and/or 6hrs prior? What justify the reason for not fixing the superblock on the rising side if not at the peak itself (but instead around 21PM-22PM)?
Nothing is wrong! it was kinda expected that after the high of the first record, it would become cold... if the record is broken every week it stops being news after 2 or 3 times...
Anything that's new will definitely made it into news. The idea with Riecoin Project should be staying in the lead of world records and gauging potential competition from various form of technologies (fairness apply here) - makes them staying out of the news.
Instead of focusing on superblocks and world records, how about focusing on merchant adoption and distribution to newbies?

I'm afraid we're not ready for merchant adoption: volume is not that high, and merchants would sell and convert to fiat immediately making the price go down. I see Riecoin as a scientific research project that pays with actual coins (instead of just "fun" like those math projects in BOINC), but it's not
yet a currency for everyday use.
Distribution to newbies OTOH is something we need right now.
The not yet a currency (or utility) for everyday use has to start soon or later.
