I would suspect that unformatted text would be faster (although I haven't done this specific activity).
Sequencing refers to the flow of the formulas (left-to-right, then top-to-bottom, etc.). But also sequencing of the worksheets themselves. The naming convention becomes critical at this point. When I start working with someone to rectify the problem, I tell them to have all data worksheets first (so, every datasheet would have a name such as A1_Data1, A2_Data2, A3_Data3, etc.). Then you want the first set of formula sheets (B1_Formula1, B2_Formula2, etc.). These can pull data from any data worksheet, and any initial formula worksheet prior to it. So B3_Formula3 can pull from B1_Formula1, but not the other way around. Then if you have another set of formula sheets, then would be C1_Formula1, C2_Formula2, etc. Again, they can pull from any Data sheet, and any initial formula sheets. If you use Display worksheets that draw from each of these, just be sure to pull from previous ones. I took a very inefficient workbook of 19 MB that someone "developed" over a period of time that took a LONG time to re-calculate. After I was done, it was 4.5 MB and took less than 5 seconds to recalculate.
It also depends on what type of formulas you use. Some take more time/RAM to calculate.
