A lot of research has been taking place in attempts to understand how runecrafting works and can be optimized.  It has been confirmed that when a rune is placed into an item, the strength of that stat is affected by the item's level and the rune slot number.
 
Below shows the percentage of a rune's value that is applied in the corresponding slot:
Slot 1 Multiplier - 100%
Slot 2 Multiplier - 78%
Slot 3 Multiplier - 67%
Slot 4 Multiplier - 57%
Slot 5 Multiplier - 51%
Slot 6 Multiplier - ??
 
I don't know if any six slot items exist yet for an owner to check the runecrafting table and see what weight is applied to the sixth slot.
 
The next table shows the value of the first rune in relation to an item's level.  Colors, obviously, indicate the color of the gear.  Uncolored items were simply added before I began color-coding.  They will be updated upon confirmations.  The values in column three are the quotient recieved by dividing the item level by the rune's strength. 
 
 
The results, thus far, are puzzling.  In most cases, a rune's value can be derived by taking an item's level, dividing it by 116.5, and rounding to the nearest integer.  However, when a quotient varies too far from this (e.g. 1749, or 1430) the formula breaks.  Instead, I began to theorize that rune strength was assigned in steps (i.e. above 1825 grants 16, above 2065 grants 18, above 2240 grants 19, etc.)  This worked for a while... until I received the data from 1318, 1319, 1322, 1430, and 1434.
 
Unless a dev wants to step in and demystify the rune formula for us, I need more data.  Since I think that plea will go unanswered, I'm going to instead ask for help from you all.  If anyone can provide a screenshot of an item with level and rarity not indicated above, that has a rune in the first slot, I will add it to the list and continue to study how the values are assigned.  For the sake of not having to do this all over again, please also provide the type of rune that has been placed in the first slot (general, set, elden).  While not included in the current chart, I will be updating it to reflect this information shortly.
 
Please note: screenshots that do not include the item level cannot be used.

Just gonna necro this.
 
Awesome info. I've been trying to figure this out myself. Has anyone done any more research into this?Allow me to quote a reddit post on the same subject:

Interesting question. From the top of my head those are the ilvls / respective bonuses for first slot:
2429 -> 21
1904 -> 16
1619 -> 14
1322 -> 11
So it seems to boil down to about ilvl * 0.0085, or 0.85% (rounded mathematically)
