Do you use charts or do you use formulas for figuring out things?

When looking for things that are in charts or can be figured out by a mathematical formula,

which do you usually do?

For example - I just found a chart that shows what size to cut squares for a finished size D9P.

It confirmed the formula that I (finally) figured out on my own.

I will probably use the formula because it is easier for me to dredge that from my mind than to relocate a chart from somewhere.

I would think that if I could remember to file the chart in a handy place, I'd use it. But I usually can't find those type of things once I've "arranged" things in my sewing room!

I usually try to figure things out myself. But a chart for such things as what size to but setting triangles is real handy. So I guess it depends on what I need.

I have to look up quilt stuff every time, although I do like charts for non-sewing things

I don't print out or keep charts, but I do bookmark them (yay Pinterest!) so I can look them up easier. For instance, a chart of fraction-to-decimal converstions (i.e. 5/8 = .625) and a chart of how big to cut setting and corner triangles for blocks ranging in size from 3" to 20".

If I have to pick, I prefer to know formulas, because knowledge is power! If I want to figure out something that isn't on a chart, I don't have to guess.

I do like charts, though, and make my own little 'cheat sheets' for things I need to know often. Or info like bed sizes; I don't think there's a formula for that; so I have a little chart.

So for me, best is a chart with most common usage, with the formula included for anything else.

I try to keep from losing too many brain cells by attempting to work out the math on my own. I did, however, create decimal conversion and yardage to inches charts for myself.

I have a loose leaf notebook with plastic page protectors in it. Charts go in there, as do my math calculations if I don't have a chart.
