ahh, line on graph must go up, huh?

this isn't a critique of the suggestion you didn't make which I assume you meant to of: everyone should always be seeking out new ideas to improve the status quo. But the meme that if you're not improving what you're doing has no value is a trash take. CPR hasn't changed dramatically in decades. Good chest compression is still the single most important thing if you want to survive to hospital discharge. But you're right, the paramedic's skills who isn't inventing a new method has no value.
