In addition these ones have stay silent for a year:
prime fact current days
exponent bits iteration run / to go / exp date updated date assigned
4300291 D 61 447.1 -24.8 35.2 21-Mar-98 18:45 21-Mar-98 11:03
4369949 60 473.5 225.9 285.9 22-May-98 13:13 23-Feb-98 02:21
However, these ones seem (somehow) to follow the rule?
prime fact current days
exponent bits iteration run / to go / exp date updated date assigned
4472627 61 1509116 216.4 196.0 81.0 04-Jun-99 15:27 07-Nov-98 04:35
4692539 61 1337470 163.3 177.8 57.8 08-Jun-99 08:07 30-Dec-98 06:11
4742407 61 3604480 292.8 48.8 53.8 04-Jun-99 10:17 22-Aug-98 19:59
4746997 61 45.3 26.6 60.6 11-Jun-99 04:27 27-Apr-99 06:03
4786079 61 1.3 92.7 86.7 10-Jun-99 06:29 10-Jun-99 06:24
4854439 61 2818048 214.7 52.3 66.3 10-Jun-99 21:41 08-Nov-98 22:46
and many more...
P.S. While I was writing this message, I recieved the message of Jeff Wood
explaning
than the check is machine based and not number base which explained this
behavior.
