Average Annual Return [Table Text Block]	AVERAGE ANNUAL RETURNS FOR PERIODS ENDING SEPTEMBER 30, 2024 1 Year 5 Years 10 Years Adirondack Small Cap Fund 22.28% 13.31% 7.31% Russell 2000 Value Index * 25.88% 9.29% 8.22% iShares Russell 2000 Value ETF 25.45% 9.05% 8.04% Morningstar US Small Cap Broad Value Extended Index * 25.20% 10.81% 8.45% * The Fund has changed its broad-based securities market index (benchmark index) from the Russell 2000 Value Index to the Morningstar US Small Cap Broad Value Extended Index. While both indexes seek to set forth the performance of the small cap value segment of the equity market in the United States, as can be seen in the return numbers above, the Fund believes the Morningstar US Small Cap Broad Value Extended Index’s comprehensive and consistent tracking of the Unties States small cap equity universe is closer to that of the Fund.
