The purpose of this post is to share some crunching I did with the invention salvage. The charts that follow rearrange the salvage visually in different ways that haven't really been touched on, and might prove helpful for answering some of the more esoteric questions people have. What this post will *not* do is provide a lot of explanation of the basics of the invention system because that has already been covered extensively by other people. This info also avoids being subjective by not taking into account the popularity of certain sets or recipes over others.
First, a couple spreadsheets that will help you find the salvage you're looking for:
Salvage Distribution by Enemy Type
These charts provide a reference for which enemies drop what salvage at what level. Pages are separated for Paragon City and the Rogue Isles.
Enemy Distribution by Zone
These charts don't specifically tie in to the inventions system, but they will help you know where to go to hunt for the baddies you need. Pages are separated for Paragon City and the Rogue Isles.
(KEY: Green = city zone, yellow = hazard zone, red = PvP zone)
The next spreadsheets are where the main work was done for this post.
Salvage Distribution by Recipe Rarity
These charts total each salvage piece by the rarity of the recipes in which it is used. Totals are given for Common, Uncommon, Rare, Very Rare, and PvP recipes, with percentages of the total for each category. Pages are separated by the level of the salvage (low, mid, high).
Salvage Distribution by Drop Pool
These charts total each salvage piece by the drop pool of the recipes in which it is used. Totals are given for Pool A (Common, Uncommon, Rare, Very Rare), Pool B, Pool R (formerly pools C and D), PvP, and Special (for Winter's Gift) with percentages of the total for each category. Pages are separated by the level of the salvage (low, mid, high).
Salvage Distribution by Origin Type
These charts show the quantity ratio of magic to science salvage that is used in each set recipe for each level range. I've also included the drop pools of each recipe for easy reference. I find that viewing them in this chart format makes it more apparent that there are patterns for the drop pools between similar set types (i.e., ranged and melee damage, all the mez sets).
Salvage Distribution by IO Set Category
These charts total each salvage piece by the set IO category in which it is used. Pages are separated by the level of the salvage (low, mid, high).

Salvage Distribution by Enhancement Attribute
These final charts total each salvage piece by the attribute(s) it enhances within each recipe. For example, if the salvage is used in an Acc/Dam recipe, it counts once for Accuracy and once for Damage. (This is what you would use to see if Boresight really *is* used more for enhancing Accuracy.) Pages are separated by the level of the salvage (low, mid, high).
