So your landing GS will be 20 kts less than V Ref. Say VRef 100, then fly whole approach at 120 GS. Your IAS will be 140 at 2500 and 100 on landing. Just what you were looking for- no? A perfect touchdown speed. Not approx.
You are dangerously in error. You say you are flying 120 GS on the whole approach. There is a 20kt tailwind at the top and 20kt headwind at the bottom. That means your IAS will be 100KIAS at the top and 140 at the bottom. Great job shooting your own method in the foot with such a convincing demonstration of how easy it is to get wrong. Good news is you get to practice a stall recovery and a touch and go in one approach.
