RANK Duplicate Numbers Without Missing In Sequence?

Attempting to do a spreadsheet for my golf club, to record scores, etc...

Managed to get it to pretty much what I want despite some very extreme looking formulae! So for some scores such as 56,56,57,57,54,54, Rank would just give me 3,3,5,5,1,1, so I have put a second column next to 56,56,57,57,54,54 where I input scores to seperate ties (better back nine scores), so in the above I would have for example 30,29 next to the two 56s, 27,29 next to the two 57s, and 27,28 next to the two 54s, so the rank would return 4,3,5,6,1,2. I have gone three stages further, so if, the back nine score was also tied, I have a column for the last 6 hole score, the last 3 hole score and even the last hole score. This is some serious formulae at this point. However, I now want the OPTION to rank the original data as 2,2,3,3,1,1 if I don't put any data in the back nine column.

This is so that I can input doubles scores on the same spreadsheet as singles scores, so if two people shoot the same score in singles I can input the back 9 scores etc to decide who comes out ahead, but in doubles I would just leave the back nine score blank, and then two people would share 1st in the rank, but then I need two 2nd ranks NOT 3rd ranks as it currently is.

Just so you can see how complex it is the current forumlae in the rank is here is an example:

=IF(O7="","",IF(K$2="MEDAL",RANK(O7,O$7:O$255,1)
+SUMPRODUCT(--(O7=O$7:O$255),--(P7>P$7:P$255))
+SUMPRODUCT(--(O7=O$7:O$255),--(P7=P$7:P$255),--(Q7>Q$7:Q$255))

[Code] .....

There are other things in there to sort out a few other issues as well, but I cant see the wood for the trees so to speak, to get it todo what I want!

I have also attached a sample from my spreadsheet to better demonstrate what I want!
