Marco, <br>
<br>
There was a time in the near past when +/- 10% meant that every module
shipped was at least -5%. Things have improved. <br>
The copy of the SW 245 spec sheet that I just downloaded has a red note
explaining that every module is above nominal in their flash test. The
+/- 3 tolerance may be largely uncertainty in the accuracy of the flash
test equipment, procedures, and in how the flash test correlates to the
real world. In other words it is a CYA operation.<br>
