I would agree with you, Bob.
</div>
<div>
</div>
<div>
I think Andrew's concerns are unfounded.
</div>
<div>
</div>
<div>
The only time I have ever seen a flash or EEPROM "wear out" due
</div>
<div>
to exceeding the number of read/write cycles is when my code
</div>
<div>
had a bug and was stuck in a loop.
</div>
<div>
</div>
<div>
And even then it only "wore out" the 10-bytes I was writing to.
</div>
<div>
</div>
<div>
Have never heard of it happening with even extreme use.

<br/>> Hummh. I have about 8 or so D7's between my oriingal prototype and all
<br/>> the ones at work, and so the age is from 15 years old to about 10 years

<br/>> Yes, but 100,000 cycles is sure a long long time. Let say 20 entries per
<br/>> marathon 5 marathons a year, that is about 1000 years life. I doubt even
<br/>> Kenwood will be around then...
