Balance Sheet styles analysis

[mpreiss9]

Because I'm doing my own tag standardization outside of edgartools, I need to validate in-balance statements from the raw xbrl data. To do so, it's helpful to understand the structure of statements as filed. Not surprisingly, there is huge variability in styles between companies and even years for the same company. To anyone else that's facing this problem, here's an analysis of Balance Sheet styles for a sample of 2,670 filings across almost 300 non-financial companies, mainly mid and large-cap across many industries. The styles are represented by their key subtotals, in the order they are presented.

0.2% Liabilities, Equity, Equity including Minority Interest, Liabilities and Equity
1% Current Liabilities, Equity including Minority Interest, Liabilities and Equity
0.04% Current Liabilities, Equity, Equity including Minority Interest, Liabilities and Equity, Liabilities
12% Current Liabilities, Equity, Equity including Minority Interest, Liabilities and Equity
10% Current Liabilities, Equity, Liabilities and Equity
6% Current Liabilities, Liabilities, Equity including Minority Interest, Liabilities and Equity
26% Current Liabilities, Liabilities, Equity, Equity including Minority Interest, Liabilities and Equity
31% Current Liabilities, Liabilities, Equity, Liabilities and Equity
1% Current Liabilities, Noncurrent Liabilities, Equity including Minority Interest, Liabilities and Equity
2% Current Liabilities, Noncurrent Liabilities, Equity, Equity including Minority Interest, Liabilities and Equity
4% Current Liabilities, Noncurrent Liabilities, Equity, Liabilities and Equity
1% Current Liabilities, Noncurrent Liabilities, Liabilities, Equity, Equity including Minority Interest, Liabilities and Equity
4% Current Liabilities, Noncurrent Liabilities, Liabilities, Equity, Liabilities and Equity

If there is any interest, I can provide this for Income Statements too, but there are way more variations there.
