Try to stay > within 1-2 %, and you'd probably be safe... o.k. 2% times 9 = 18% per char. Assuming we are sampling in the middle we have 50% margin, right? so 18% will be o.k. , 3 or 4 percent should still work, anything above this *should* fail. this would make for an interesting experiment ... > > Jan-Erik. > > > > -- > http://www.piclist.com PIC/SX FAQ & list archive > View/change your membership options at > http://mailman.mit.edu/mailman/listinfo/piclist > > > -- > No virus found in this incoming message. > Checked by AVG Anti-Virus. > Version: 7.0.308 / Virus Database: 266.11.9 - Release Date: 12/05/2005 > > -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
