Thanks for the input, this is my first few days in working with a manual machine (certainly more art to it than I had given credit for).
I dosed this morning to around 17g but the extraction was slightly quicker than the target 25-30 (15 seconds or there about).
Unfortunately I am yet to acquire a grinder (wife was none too impressed that I invested in the manual machine when we have a "perfectly fine Nespresso machine"). Had my local roaster dial in this grind (beans roasted 16/9) so I am having to adjust my tamp to hopefully get the desired extraction.
