Hi Vahe,

I re-ran my replay with maxslope = 0.25 (instead of 0.025), but 
unfortunately the effect is very small. I get only an insignificant 
increase in the tracking efficiency, from 90.53 to 90.76 %. See the 
attachment.

If you get ~97% efficiency, it seems like you've fixed some other 
problem, too.

Can you send me a copy of your database file?
