no less than or nothing less than

[tankobe]

A question revised from OG10(hope revise it correctly)
Even their most ardent proposers admit that no less than(or nothing less than) a further qualitative or quatitative analysis is necessary before a research project can meet the goal of providing the eterprise's perspetive needs.
the question is about no less than . according to OG, no less than in my sentence is needless; the most effective sentence is:
Even their most ardent proposers admit that a further qualitative or quatitative analysis is necessary before a research project can meet the goal of providing the eterprise's perspetive needs.
no need to chanllenge the OG opinion, i just want to know can we use no less than or nothing other than in the comparable context. could you provide some examples(acccording to LONGMAN, these two phrase can mean 'emphasize')?
