Did F.I.M. on one, Topped the other

Ok. So I looked on the net extensively and after an hour pieced together what the heck the real difference was between topping and F.I.M.ing. If you are experienced with both techniques, this is for you, because I need your feedback on my explanation. If you need help in trying to understand the difference, and how to do each, this is for you as well, because I'm trying to elucidate the techniques for everyone.
So, here it is, my explanation of the difference.
Topping refers to the technique of cutting off a top portion of the plant (usually just the cut is between the very top node, and the second to top node), so that the nodes just under the cut you make become main branches and eventually colas. In this way you get two main colas instead of one. Although the colas will be smaller, the general consensus is that the amount of take-home weight after harvest will be bigger.
I have a before and after picture of a topping I did on one of my 25 day old white widows.
F.I.Ming *stands for fuck I missed*, is removing 80-90% of a new leaf set that is coming out of the main branch, just above the highest node. In other words, you're not cutting the branch, as in when you top; you are cutting the new leaf set coming out. F.I.M.ing can yield up to 8 new colas, because you are cutting the newest leaf set, and hence the newest (and fastest growing) cells nearby react by growing many different branches. It is an awesome thing if you get it right. Actually it's not too hard to do, just need a steady hand, and know where the heck to cut.
Here are the pics.. The topping pictures are self-explanatory and easy to see.. when I show the F.I.M.ed plant i'll try to explain a little more.
Before the topping on one of my white widows:
Immediately after the topping:
Ok now the F.I.M. The plant I chose to do this technique on had a new set of leaves that were coming out and still fairly small (about 1 cm in length). The set of leaves were going to become a set of 2, 5 leafed fan leaves. I made a HORIZONTAL cut 80% down from the tip of the new leaf set.
Here is the before picture of my 25 day white widow:
And here we see it after I make the cut. Notice I did NOT cut the branch, but the new growth that was going to become the next set of fan leaves. 80% of that growth was removed:
The red circle shows you the cut and the remaining part of the new growth.
Ok, comments from experienced growers are welcomed =)
Hope that clears things up for people.
