I meant, with stripboard one tends to cut tracks over holes, with a drill bit, meaning the gap can be >3mm between copper, which can be too much for an 0805.  But I tend to cut tracks between holes anyway, so it doesn't matter.

I also prototype with SMT parts on perforated prototype boards. Originally I was inspired by Elm Chan, (Google if you haven't seen his projects) I can't match his neatness but I can make stuff that works.

When I prototype on blank copperclad I sometimes put polyamide tape down under pins I don't want to connect to the ground plane. For DIPs I bend the thin part of the legs I want to connect outward and solder the ground pins butted up to the board. I don't like to flip the chips upside down, I have too much trouble keeping track of what is what and which pin is which.

It is surely amazing.

I think the best way is not to overthink it. You'll find the best method of ad-hoc prototyping by just doing whatever needs to be done, in that moment, when you need it, without thinking too much about whether this is "the right way". After all, lab prototyping is all about one-offs, and your workflow, so do it the way which is quickest to you. These prototypes often don't need to be robust.

I linked the Elm Chan on the previous page, as an example of what can be achieved.

However, I agree with the overthinking and his work seems like the returns may not be so rich.

I overthink myself and it definitely slows me down and even stops me completely.  Have a look at Mike's LCD hack to see an example of what can be achieved when you don't mind what the rig looks like
