John Driscoll does an excellent job of correlating Daito ryu and aikido techniques here on Aikiweb. The end result is a very high percentage. Mochizuki laments the fact that Ueshiba pared down the Daito ryu syllabus ... not that he changed it.
There are, after all, only a limited number of ways to bend human anatomy.
But I think most aikidoka would say that aikido is more than the sum of its techniques. Most students of Daito ryu would probably say the same. To truly appreciate both the similarities and the differences in the two arts, I suspect that you would need to have substantial experience in both.
