Apparently, when using Safeguard, it is better to use 5 Enhanced Cores, there will be a gain of .5% more success chance, added to the upgrade points.
Superior Cores are just for true RNJesus believers that wants a +2 while still nullifying the -2 fail.
Since +9 up to +15 is 36% chance, many people will be content with 4,000 points to have a round number of 40%.

In sum, here's what you can choose.
With Superiors,
Nullify the -2 and try your luck for a small chance of +2 (5%).
With Enhanced,
Use enhanced cores with the maximum of upgrade points while still nullifying the -2. (better option)
3,5k pts + 0,5% from 5 Enhanced Cores equals a nice 40% chance of success!
in the +9 to +15 bracket I'm speaking.
Although the success +1 are the same from +10-15, there's a tiny (but from experience, huge and frustrating) gap of 2% in the fail department, switched between -1 and -2. Summarized here:
