Since you seem to be so concerned about it let's look at the scores you gave:
Code:
.....................................GR/SR......FT
perihelion precession disparity......1..........1
gravitational light bending..........1..........1
galactic rotation curve..............0..........1
Hubble's law.........................0..........1
black hole...........................0..........1
kinetic time dilation................1..........0
total................................3..........5
Well we already discussed your 'explanation' of Hubbles law. In order to provide a handwaving 'explanation' you have to redefine a prediction your theory made that was internally inconsistent in such a way as to cancel out the bad result. You then took this fudge factor and claimed it was an explanation of Hubble's law. So... No arbitrary or introduced energy or velocity factor there at all. By your own scoring system your idea does not explain Hubble's law at all. 3-4 GR to FT.
Black holes. Well, you are completely wrong here too. GR gives a very good description of them and your description is based on a faulty understanding of them. You pull in a few verbal paradoxes and claim victory? Nope. so. 4-3 GR to FT.
Galactic rotation curves. The dark matter GR 'introduces' is backed up with several other observations that are not purely gravitational. So it is not arbitrary. 5-3 GR to FT.
Code:
.....................................GR/SR......FT
perihelion precession disparity......1..........1
gravitational light bending..........1..........1
galactic rotation curve..............1..........1
Hubble's law.........................0..........0
black hole...........................1..........0
kinetic time dilation................1..........0
total................................5..........3
By your own scoring system you should give up on FT and study GR more.
