I use the approx.:  (1 + small number )^ n ~~  1+ n ( small number)

3% (of whatever)  is not a a small # so  1.06 differs from 1.0628,  etc.
by about 5% error.  Nevertheless, multiplying -2 by -0.03 is quick.

bc, who finds:  delta  I = - 2R (delta R) equally inaccurate.
(Intensity and radius, respectively)
