Good point. The real risk in skipping days is that you might forget altogether some of the cards that were due for review. But the Anki default is to review often enough that probability of recall for each card is very high, so if you're only skipping a few days at a time this is not a huge concern. Capping the amount of cards you do per day has a similar effect; Anki will prompt you with the highest-risk cards first, and some will be left unreviewed for the day (hence, practically skipped).
