clarification on tax rate parameters

i hope this doesn't sound like nit picking. i truly admire all your work and appreciate having the app.

regarding the two parameters INVESTMENT TAX RATE and INCOME TAX RATE, and per the user guide, i believe a better title for the former parameter would be one that doesn't imply it's a tax rate. as i understand it, it sets the fraction of the investments withdrawal than is subject to tax. an example of a title that seems appropriate to me is: INVESTMENT WITHDRAWAL TAXABLE FRACTION.

bravo for this marvelous tool!

oops. i just read a forum item that states that taxable investment returns are taxed annually. hence, the parameter i questioned probably is a tax rate. sorry for not more-thoroughly researching.
