Further to yesterdays post, I performed some additional optimisation to the database used to test the effectiveness of the improvements to YCV calculations. This has demonstrated that you should attempt to optimise existing cube structures as much as possible before trying Single-Time version cubes.  The performance of Single-Time version cubes is influenced by optimisations far more than Multi-Time version cubes, and the gap between them is considerably narrower than it is if no other optimisations have been made.

So my conclusion is slightly modified. Make sure that you have exhausted all possible optimisations before applying a Single-Time version approach to a cube. Otherwise you may get misleading results.

Attached is a modified version of the original paper reflecting the changed results and comparing the results before and after applying other optimisations.
