     note: `drip applies NFP's rules for calculating infertile days at the start of the cycle (see the ${links.wiki.url} for more info). However, drip does not currently apply the so called 20-day-rule, which determines infertile days at the cycle start from past cycle lengths in case no past symptothermal info is available.`
