DWH says: There is apparently no mathematical symbol desinnating light
speed percentages so I have devised one, modestly using my lower case
initials. A (dwh) of.1 = 10 percent of the speed of light and so on up
to a (dwh) of 1.0 = 100% light speed, 1.1 = 110% etc. The equation I
use for determining rise time is (1 + (dwh) x 21) = rise time in Earth
days!
