Full float + 2 coverts = deflationary for the collection.
Valve must be studying the armory, seeing an oversupply of good wear coverts, so to appease the demand they lowered the supply.
Compared to the M4 Fade Factory New every 811 unboxings, each new FN covert is 1 in 52k
The new skins are FULL FLOAT.
This means: To unbox the red you want (1 in 1562, as any covert is 1 in 781) means the exact red you want, then it being a 3% chance to get it in FN.
It's a 1 in 52,066.67 or (0.00192%) chance to get a FN Specific Armory NEW RED.
