single table ITM %s?

[randommuppet]

is 40% plus sustainable long term? am i wildly ambitious/unambitious?

i havent really been tracking my sng results (i know, i know) until recently but in a discussion with a friend at a live game he told me his ITM was 40% + over the last year (cant remember the sample size).

i seem to recall someone stating here that this kind of ITM % was unsustainable long term - or was i dreaming?

cheers
