How'd you arrive at those values?
Fair question. I will explain below.

1. Thank you for making me take another look. You made me spot an error. I have a table of co-efficients used for adding an effect for different armor types (explained below). I had added a entry to the table, but had not udpated the table's definition to include an additional row; "Steel Riveted" stopped being within the defined table; Steel riveted (less effective plates of steel riveted together) was being picked up as the stronger "Steel" (basic steel armor, 1940 to 1955)

After correcting the table, a soem of the armor values changed; 5s becoming 4s, some 4s becoming 3s.

2. How does Uncle Ted make armor sausage?

I built a spreadsheet (of course). The armor section works like this. I had collected a raft of data for WW2 and post-WW2 military vehicles for Advanced Tobruk, including armor (detailed to facings and slope of armor). Using that analysis, i compared those sheets to some of the existing older vehicles in the T2K cannon (which is, not surprisingly, inconsistent, even with specific time periods)

What I came up with was that for steel armor:
for WW2 steel armor (1940 - 1955ish) = an armor point for every 7mm;
for more modern steel armors, one for every 5mm

Modern armor/5
Older armor/7

This is complicated by average slope of the given armor face, which may drive increase the value of by up to a factor of 2.

This is complicated by the armor type. For vehicles in the period of steel armor (basically, every tank before 1975, and several since), this breaks down into solid or welded armor and bolted (bolted includes most armored vehicles built before 1940).

Remember that coefficient I mentioned above? This is where armor type gets factored in. These vehicles are mostly all endowed with bolted armor plates.
(exceptions: VK-31 & A2E1 Medium Mk I have steel)

Now, T2K uses one armor scale for vehicle vs Vehicle and personnel combat, which leads to a few peculiarities at the bottom o f the scale. Using the scale outlined above, many of these early tanks would have an armor factor of 2, which would not keep out contemporary small arms (Lee-Enfield rifle, 8mm Mauser, Lebel etc).

So I include a check to provide "design for effect" - if I have armor values and the process above gives an armor value of less than 3.6, it adds 1. This ensures that these early vehicles can shake off small arms.

Modern MBTs (and some recent IFVs), where they seldom mention armor thickness directly, and their armor type is not steel are handled differently.

And now I have some other files I need to correct.....
