Query about a formula I'm working on

[Kuda]

I was wondering if it is possible to make this query less longwinded?

=(IF(D17>0,(((A1-C17)/(A1/D17))+C17))+IF(E17>0,((A1-(((A1-C17)/(A1/D17))+C17))/(A1/E17))))+IF(F17>0,(A1-(((A1-C17)/(A1/D17)+((A1-(((A1-C17)/(A1/D17))+C17))/(A1/E17)))+C17))/(A1/F17))


A1= max value
C17=base value
D17,E17,F17= variable value's

I've been working on the Value for a Calc for a game I've been playing lately.
I'm using it to work out damage resistances but I feel the formula could be streamlined but for the life of me my brain has gone blank.
Example:
A1=100
C17 = 60
for arguments sake lets say D17, E17 and F17 are all = 30
the formula would get the max percentage and work out what the boosts would be for each variable based on the difference between the max value and the base value.
The answer given by the formula above would for this would be 86.28

Does anyone know if there is a way to streamline the Formula? without obviously using extra cells to store hidden values.

Two ideas:
1) Use Insert|Name and define myfactor as
=(Sheet1!$A$1-Sheet1!$C$17)/(Sheet1!$A$1/Sheet1!$D$17)+Sheet1!$C$17
This makes the formula
=(IF(D17>0,myfactor)+IF(E17>0,((A1-myfactor)/(A1/E17))))+IF(F17>0,(A1-((myfactor+((A1-myfactor)/(A1/E17)))))/(A1/F17))
2) Do away with IF's to make more readable
=(D17>0)*(myfactor+(E17>0)*((A1-(myfactor))/(A1/E17)))+(F17>0)*(A1-((myfactor+((A1-(myfactor))/(A1/E17)))))/(A1/F17)
best wishes
