ussually a refresh rate considerer optimal is ~75Hz...

I am guess the industry changed units so that people wouldn't be driven away with much less values for refresh rate then is considered good on a CRT..
well, IDK.., I think I am going to ask my friend what his response time is.., cause I thought his worked nicely

You can't compare refresh rates like that, because LCD's work in a completely different way to CRT's. There is no flicker with an LCD monitor, like you get with CRT's, and so the refresh rate is irrelevent. The 25ms response time that you quote is the time it takes for a pixel to change from one state to another, and which affects fast moving images such as games. It has nothing to do with refresh rates.

You can sort of work out the rough equivalent response time of a CRT monitor on the grounds that as the pixels have to be refreshed every x number of times per second, then so the response time must be the same. The formula is T = 1 / F, where T is time in seconds and F is frequency in Hertz. So a CRT monitor at 75 Hz is refreshing every 0.01333 S, or just over every 13mS.
