Before any variations are attempted , off air stats are needed , there was close to 100 instances of V155 in use since its launch , with only 1 error that would be 1% . Occurrences will be statistically related to user numbers Where it is unfortunate 'real' calls are produced , the time delay presents a simple , at a glance spot-check , the integrity of the original system has not been compromised, at the moment the list has a 8 day life , this could be reduced , but with the 7 day operating cycle , 8 provides overlap 73-G, -------------------------------------------------- From: "Mike Dennison" Sent: Wednesday, January 07, 2015 3:37 PM To: Subject: Re: LF: New version OPERA >> ''Opera Dynamic'' << > Sorry, Graham, but you are wrong.
