Well done, Artful Codger. I read you clear and precise.

Addition: I've learned at school yeshcho-da raz, not yeshcho-to (cf. ay-da in the fill up line).

The dodgy sound ui is the same as in the Turkish dotless i. To pronounce it form your lips as if saying i (ee), but articulate the sound in the back part of the oral cavity, where the u (oo) is formed, and try to pronounce the German umlaut ue (the u with the two dots).
Difficult? So it may give you an impression of the difficulties we poor librarians have to endure ...
