Now you have completely changed my thinking process....
I am confused as well. But the following explanation (seen in another forum) makes sense.
Check this out -
"1. Is "will had" correct usage ? 'Will' is used as a noun here. 'A powerful will' means a powerful desire, a powerful decision or intention. I think you are mistakenly looking at 'will' as a verb form here, but it isn't. If you now look at the sentence again, I think you will understand it better.
First of all why do we need "had" here ?? Simple "made" in place of "will had made" makes the sentence correct, isn't it ?? 'Had made' is just past perfect. Yes, you could use 'made' instead here. It's a matter of style and emphasis.
2. will ". . . have made" work in place of "'... had made" ?? No, there's no relevance to the present here.
Best wishes, Clive"
Now try the example Karen gave - all makes sense.
'It's similar to saying "By the age of 8, Mozart had written pieces of music that blew everyone away." It's not that there are 2 past *events*, exactly; rather it's that there's a deadline -- the moment at which Mozart turned 8 -- and saying that he *had written* these things before that moment.'
Hope this helps. Anyway thanks dude...for making me dig into this!
