Strange result

I just tried to explicit CASE but it is then SLOWER :

'CASE 33 TO 126: index% = (z% - 33) * array(0) + 2
CASE 128 TO 133: index% = (z% - 34) * array(0) + 2
CASE 135 TO 140: index% = (z% - 35) * array(0) + 2
CASE 142: index% = (z% - 36) * array(0) + 2
CASE 144: index% = (z% - 37) * array(0) + 2
CASE 147 TO 151: index% = (z% - 39) * array(0) + 2
CASE 154: index% = (z% - 41) * array(0) + 2
CASE 174 TO 175: index% = (z% - 60) * array(0) + 2
CASE 225: index% = (z% - 109) * array(0) + 2
CASE 183: index% = 118 * array(0) + 2
CASE 212: index% = 117 * array(0) + 2

This is slower...
