Good stuff Brad, and welcome. Wouldn't worry overly about the occasional squirt if the coffee tastes good. I too trundled along without the use of scales for some time (though I think my dosing in the standard double basket that came with my machine was fine). When I tried using VST/Synesso baskets (just an experiment) I initially had some trouble....then worked out that I too was throwing about 23g of coffee into nominally 14-15g baskets. Once I dropped that to somewhere b/w 18-20g (depends on bean / roast level) all was good again (and yes...this does result in a slightly lower dose level relative to the shower screen...but within an apparently acceptable range....I don't care what pucks look like). I don't use the scales regularly but they are a fair reference point when one is needed. When dialling in a new bean I usually weigh one shot for interests sake. What's even sillier, is that every now and then I weigh the extracted coffee...just so that I can calibrate my judgement of volume for a particular bean. Not for everyone, but helped me.
