Yup I've read your descriptions. I was asking for more because in my quest to alleviate the gps issue I've come across other variables that are not in your patch, for instance C2K_HOST and ENABLE_WIPER and I could not find adequate explanations of their meaning.
I've played with INTERMEDIATE_POS and ACCURACY_THRES, currently they are set at 0 and 0 respectively so I will try your suggestions right now.
The two variables above were removed around v1.3 of this patch. They are no longer useful. C2K is no longer supplied. Its server is gone and not replaced by the contractor.
WIPER was useful in older devices, but sent a lot of newer one's into frenzy mode. Also, it doesn't do so well in the middle of nowhere. I'd have to review my actions/notes to get a handle on what it was for. It's been a year so I don't recall.
