MN 10 is a fake sutta that includes the five hindrances in the 4th satipatthana. Therefore, if the meditator practises for seven days: ‘I have sensual desire in me’; they obviously will not make any progress because there cannot be any progress when the five hindrances exist.
This said, if proper satipatthana (such as described in MN 118) is practised continuously for seven days, i.e., without any hindrances for seven days and with proper samadhi based in 'letting go' (per SN 48.10 and the end of MN 118), then, yes, certainly that meditator will be a stream-enterer and certainly they can expect one of two results in their life: enlightenment in the present life, or if there’s something left over, non-return.
It is important to distinguish between 'actually practising satipatthana without hindrances' and 'attempting to practise satipatthana with hindrances'.
If a meditator sits one or many 10-day Goenka, Mahasi or IMS satipatthana meditation retreats but continues to have hindrances or uses a wrong method, then this is not actually practising satipatthana.
In order to develop these Four Kinds of Mindfulness over 7 days, one needs to have perfectly balanced faculties for the entire 7 days (which depends on one single moment of Right View).
Ajahn Buddhadasa explained:
As for samadhi, an empty mind is the supreme samadhi, the supremely focused firmness of mind. The straining and striving sort of samadhi isn't the real thing and the samadhi which aims at anything other than non-clinging to the five khandas is micchasamadhi (wrong or perverted samadhi). You should be aware that there is both micchasamadhi and sammasamadhi (right or correct samadhi). Only the mind that is empty of grasping at and clinging to 'I' and 'mine' can have the true and perfect stability of sammasamadhi. One who has an empty mind has correct samadhi.
