Yes it's absolutely critical to replicate the same conditions when calibrating, taking OG and FG..I do hope everyone understands that however you read a hydrometer, bottom or top of the meniscus, or anywhere else, you must read exactly the same way when calibrating, while noting any deviation from the expected "null" point. Then apply that correction to every reading from there on with that same amount.
That includes careful preparation on bottling/kegging day by having the same three brew day beers you usually chug during the boil while forgetting to add the hops.
