[Lowfer] Request for comments

Thanks, Dale, for your kind words.

I am not sure that my approach is unique or even worthwhile but some of the
notes I have received, like yours, demonstrate that there is still a
interest in improving how we do things. And I think this is good.

I, too, have felt that there has to be a better way (with all due respect to
those who have gone before). Your filter method sounds a lot like a feature
of Wolf or the Grab feature on Africam. Some form of integration to
reinforce the signals. I think I can add something like that.

Please keep the comments coming.

Regards,
Mike
