I certainly did not forget that ice isn't always consistent. These charts were just food for thought. I thought that some people might find it interesting how much weight ten inches of ice has the potential to hold. That's also why I gave the disclaimer: "Who knows how accurate this chart is?" followed by "...there are different qualities of ice". Also, if you read the article from my second post, it pretty much says everything you just said about inconsistent ice, which is all true.
One thing you should take note of from the article which isn't quite in line with what you wrote:
"Contrary to what you would expect, a rapid, large air temperature drop makes an ice sheet brittle, and the ice may not be safe to use for 24 hours or more.
Charts and graphs are just that, charts and graphs. Conditions will vary greatly from place to place, and from day to day. When determining ice safety, nothing should replace sound judgment, and that sound judgment should be made at the margin. In other words, a little at a time. Don't assume the whole lake (like you said, is 4 inches) just because one drilled hole turns up 4 inches. Check a little, move a little, check again ...etc.
