Chart from Categories with Sub-Categories

Hello,

I don't quite know how to explain this, so excuse the nondescriptive title.

In this table there are 7 wound types that each have 3 size variations. There are also 4 types of bandages that have 4 parameters that affect each wound and size of wound differently.
The goal with this chart is to purvey at a glance the ideal type of bandage for each given type of wound. I do not suppose it's possible without excluding a parameter, but bringing it up here is worth a shot.

If you have any idea as to how to get a recommended treatment across in as compact a format as possible, you have free reins. I'm only just learning Excel 2016, so I'd also just appreciate any pointers to send me on my way.

Cheers.

Ideally I would like to see an overview of all bandages and how efficient they are for a given wound.

Let's say you have a large velocity wound and you want to find out which bandage you should use to patch it up as quickly as possible, you'd look at this chart and be able to point at your options.
How does a packing bandage compare against an elastic bandage in this case?

Effect is the effectiveness of a bandage to cover up the wound. Chance is the chance in percent that a wound reopens after it has been bandaged. The Min / Max values are the times in seconds until a bandaged wound reopens, if it does so.
Generally across wound types, a packing bandage thus has a higher chance to reopen, but it keeps it sealed for much longer. A basic bandage is as effective, has a lower chance to reopen, but if it does, it does so much quicker.

Should I take the average of the values for all wound sizes and eliminate a factor? Instead of a small abrasion, medium abrasion and large abrasion with different values, I'd only have an abrasion with an average value to display on the chart. That's not as accurate and comprehensive as I'd want it, but if such abstractions help form a digestible chart, I'd do it.

Should I introduce an efficiency value that is calculated based on these parameters, then eliminate wound size with an average? That would leave me with one dimension for bandage types, one for wound type and one for the efficiency.
