Here's some data you can play with.

When I looked at it years ago, I wasn't happy with a 5th order polynomial approximation. We used the following lookup table below with the IFI system (input range 0-254, output range 0-254). It wasn't perfect, but greatly improved over nothing.
Code:
0 10 10 10 10 10 10 10 10 10 10 10 10 10 10 11 11 11 11 11 11 11 11 11 12 12 12 12 12 13 13 13 13 13 13 13 13 13 14 14 14 14 14 14 14 14 14 14 15 15 15 15 15 15 15 16 16 17 17 17 17 17 18 18 18 18 18 18 19 19 19 19 19 19 20 20 20 20 20 20 20 21 21 22 22 23 23 23 23 24 24 24 25 26 26 27 27 28 29 29 30 30 31 32 33 33 34 35 36 37 38 39 41 43 45 47 48 51 52 55 59 66 68 73 79 84 92 127 127 143 144 144 144 144 144 145 145 145 145 145 145 145 145 145 145 146 146 146 146 146 146 146 146 146 146 146 146 147 147 147 147 147 147 147 148 148 148 148 149 149 149 149 149 149 149 149 150 150 150 150 150 150 150 150 151 151 151 151 151 151 151 151 152 152 152 152 154 154 154 154 155 155 155 156 156 155 157 157 157 157 157 157 157 159 159 159 159 160 160 160 161 162 163 163 164 164 164 165 166 167 168 169 169 170 171 172 173 174 175 176 177 178 179 182 183 188 191 192 193 196 203 207 211 220 229 254
