Use the formula:

#Delta% =100("NewValue"/"OldValue"-1)#

where #"NewValue" =0.35(2.3)^(x_"new")# and #"OldValue"=0.35(2.3)^(x_"old")#

#Delta% =100((0.35(2.3)^(x_"new"))/(0.35(2.3)^(x_"old"))-1)#

#Delta% =100((2.3)^(x_"new"-x_"old")-1)#

Assuming that units of the model are in years and the difference is 1 year

#Delta% =100(2.3^1-1)#

#Delta% =100(1.3)#

#Delta% =130%#
