I'm not far from you in the counting, though I have no idea how you came up with 29 AD as the date Jesus was cut off, and the meaning of His being cut off. My timeline is 33 AD on Jesus' entry into Jerusalem riding as ass, and Daniel's seventieth week being seven years of peace having everything in common until Stephen's death.Daniel 9
Vs.26 And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined.
After 434 years that end in the year AD29 shall Messiah be cut off. Jesus was crucified after he was baptized in AD 29 three and a half years later. Jesus was cut off (killed) by the people of the prince, which means National Israel or other words the Pharisees, Sanhedrin and the high priest that destroy the city and the sanctuary (meaning Christ) and the end thereof shall be with a flood (Gods wrath) that will put an end to abominations by desolation or in other words a ruin to evil deeds. Daniel 9:27 explains the definitions of desolation of abominations or the ruin of evil deeds. There is no actual Desolations of Abominations where the so-called Antichrist will take a literal throne, but the desolation will be when the beast that Satan gives power to tries to take his throne in Jerusalem, (Ref: Daniel 11:36-45). Gods’ word never defines one great Antichrist, but says there are many antichrists. The seven years that some call the seven year tribulation means three and a half years of Jesus teaching before he was crucified and three and a half years of Stephen teaching before he was stoned to death, which took place after Jesus was taken up to heaven.
Vs.27 And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.
The 70th seven began with Christ baptism in AD 29 and three years later at the end of the first half of the 70th seven sacrifices and offering ceased because Christ hung on the cross as he was the final sacrifice that fulfilled the law. From the giving of the law in 458BC when Ezra went to establish the law, or to rebuild the Spiritual city right up to the cross were the first 69 sevens. The 70th seven is from the time of the cross until Jesus comes and gathers his bride as they prepare to stand in the Holy place until the overspreading of abominations he will make desolate, or make an end to all that would not repent.
Your theology sounds a lot like that at the following URL where he attempts “Fixing the Date of Stephen’s Death.” He goes on to say “Fixing Stephen’s death (Acts 7:51-60) to an exact day involves using prophecy, which if true . . “ And I like that with Brother Edward.

My counting using year/day counting, and 360 days per year brings me to slightly different dates, and the cutting off to me is the cross.
Dan 9:24 Seventy weeks (Of blessings) are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy. (The seventieth week ended with the stoning of Stephen.)
Dear sister, it’s evident we’re not going to agree here so I will respectively withdraw, and I pray our differences doesn't affect our commitment in our individual spiritual walks, but that we can edify one another where we can.
Blessings in Christ Jesus.
