Water Temp Map Trend

This follows on slightly from my other post.. When looking at the water map is it normal for it to get to 68degs and then take a sudden ramp down to 0 correction like shown below. Or should the map ideally taper down nice and smooth to zero as a nice consistent gradual curve? The latter sounds like it should be the case but maybe someone can give some feedback. ask because where I have adjust the 500rpm line slightly I noticed it has smooth the curve slightly more than it was before. This makes me think maybe I am heading the right way with the 500rpm adjustment but just want pointers as to what other people have or consider to be normal?
Thanks in advance!

Your map 68 degrees is only 5% additional fuel for warm up. 5% at 6* degrees to 0 at 82 degrees is not a huge fall off. If the car warms up smoothly as it is, then let it be. If you really wanna mess with it you can carry it down to 3 or 4% and see how it transitions when passing through those temps and if it suits you then you can keep it that way.

Thanks for feedback. I know it is not a big drop off but the point was should it ideally be a nice smooth curve flowing out into nothing? It is pretty happy where it is but I think a nip and tuck here on the matrix around the idle cell I could make the graph smooth down perfectly. I guess the answer is try and see what happens.. I just want to know if I am chasing something I shouldn't be?!
Regarding the cells to the left and right of idle.. To the right do they want to be closer in value to idle? And then compensate with more pump? And to the left I seem to be getting a bit of Rpm hanging into lower idle coming off throttle.. So I guess I might need to lift a value or maybe I went to much already? Would be great of someone could share a matrix so I can see how it compares. The trend must surely be pretty. Similar from one car to the next?

My car does need a little more extra fuel at around the same temp 2 idle fine.In fact my water map looks a little funky but that is the only way that the car will run fine.I will grab a pic for you Leroy.
