A board in near-constant use needs to withstand repeated erasing, frequent magnet use and long stretches without a deep clean, since teams rarely pause daily work for maintenance. Specifying for this reality, rather than for an idealised occasional-use scenario, avoids a board that ages faster than expected. This also means the board is rarely, if ever, completely empty, which affects how much genuinely free space a team can expect at any given moment. This also affects how quickly a board needs replacing if the wrong specification is chosen, since a board under-specified for continuous use tends to show its limitations faster than one that was appropriately matched to the use case from the start. Teams often underestimate this until they compare notes with a similar team using a board specified for lighter use, at which point the difference in wear becomes obvious.
