I think it's fair enough? The discrepancy between a few years and 17 months is outside the realm of ordinary casual imprecision, so it seems like the author made a mistake one way or the other. I'm kind of curious now about how long it really took, and whether they just made a typo or the last year and a half felt like years to them.
