I would say that it's best said that anything between your coil and the target can alter the TID. You should't see night and day differences in the target ID but it can often times be a few points in either direction. Even something that seems as simple as moisture content will change your TID.
Here's why I was asking.
On Youtube there was a Minelab dealer who was showing his configuration on the 705 for hunting gold rings. How he tested about 49 pieces of gold and then tailored his discrimination to allow in the certain target ID numbers that went with the most gold rings.
It was very interesting, but it left me wondering, how do I know those would be the same target ID's in my dirt?

That video will show you how to miss as much as you find. I really suggest that you don't waste your time with his method.
BTW, the subject and that video have already been discussed. http://www.findmall.com/read.php?55,2154967

Not sure if that minelab dealer is a sponsor here or not. But in all honesty that guy is the most flamboyant know it all pretender amoung all the dealers. Born liar/con man. And I've met some real spaced out dealers in my time!
By rejecting so many arseabout segments, by the time the coil hits the dirt the XTerra's processor simply cannot cope with placement, and will place what should be a clean hit into and around an open bin, place a pulltab that would normally be rejected by your own tone-change judgement, and bring a rusty bottlecap that would on occasions hit a true 28 for instance - directly into one of his empty bins.
This guy is refered to by some of us as a 'nugget planter'. In the 1800's we would have called him a mine salter.
One thing I have found out is that everything effects everything else. There are no absolutes. This is the reason I hunt in all metal mode and dig everything that peaks my interest. If I notched out certain items I would not have found near the items that I have found. If you are in an area where it's feasible to dig everything then do so. You might be very surprised at what you find that ids as something different. No telling how many times I have almost not dug an item and I am glad that my instincts told me to dig it anyway.
Yes, as others have already said, everything between the coil and the target affects the TID. I hunt a lot in the woods, often with a thick layer of leaves on the ground. Depending on moisture, thickness, etc, the leaf-layer can throw my readings all over the place. It's common for me to get a "rock solid" 40-44 reading through leaves, rake them away, and then have a bouncy signal in the 20s which turns out to be junk. Lots of attenuation, reflections, multiple returns (with tiny phase shifts due to different path lengths), etc, for your detector to try to deal with.
