ESO Dragon Bones Update – random Morrowind plans documents

PTS testing: With Dragon Bones update players can buy Morrowind furniture plans with vouchers. Rolis Hlaalu, the old master writ vendor, has got an apprentice, Faustina Curio. She is selling blue "Morrowind Journeyman Furnisher's Documents" at 20 vouchers and purple "Morrowind Master Furnisher's Documents" at 50 vouchers. The documents drop random furniture plans which were added into game with Morrowind update.

Update 2018-02-06: This will change in live. From PTS 3.3.4 patch notes:

The Morrowind Furnisher’s Documents available from Faustina Curio no longer contain plans that can be found outside of Morrowind, such as Daedric or Dwarven furnishing plans.

There are about 91 blue and 138 purple plans. There might be actually few more in loot table. I bought repeatedly more documents until almost all were duplicates.

Dropped unique plans divided by style and type:

I bought about four times more documents than there are unique plans. I calculated the ratio between unique and total amounts pre style/type:

There were e.g. two unique Ashlander blueprints. First dropped five times and the other six times, total 11 (not visible). Dividing 11 by 2 gave 5.5 duplicate rate.

Looking the table, all styles and all types had rate around 4. This shows that all plans have same drop rate from documents.
