I get this values. do you get better values ?.they differ 0.2% from real value.(60 hz should be, 59.8251 is
It is correct. "NTSC/PAL mode" value is calculated rate from current custom chipset refresh rate parameters. (NTSC/PAL is only state of Agnus PAL/NTSC mode, it does not necessarily mean rate is NTSC or PAL compatible)

Note that NTSC actually is not exactly 60.00Hz on Amiga (Neither is official NTSC rate which is 59.94Hz). Amiga PAL also isn't exactly 50.00Hz.

For example PAL non-laced can have 2 rates (long field = 313 scanlines, short field = 312, depending on state of LOF bit), interlace alternates 313/312/313 which means there can be 3 different refresh rates that are all "PAL".

59.987746Hz is detected real hardware rate for vsync purposes. (Which probably also isn't 100% exactly 60Hz)
