Doubting the quick attainments of the Mahasi Tradition

***I have noticed that a lot of Mahasi practitioners seem to reach sotopanna very quickly.*** What is the difference from other methods of Buddhist Meditation and the Mahasi Method, relative to the apparent speed of attainment in the Mahasi Method? **Maybe you think Mahasi style practice does not lead to these better results?** If so, who, what, where, when and why do you think this? I hope this is an appropriate question but if it's not, that's ok :) metta **PLEASE NOTE**: I have, "**doubts** about such quick progress in the Mahasi Tradition, not **pride**" It appears, many assumed something else. My mistake, I should have been clearer.
