ciba/ilfochrome speed ratings

I plan on making a simple 8x10 single sheet ciba camera this week. I've
searched high and low (including the archives) and have found almost
nothing that states the EI of ilfochrome...

It seems a popular enough pinhole medium to shoot on so im puzzled by
the lack of info.

I have seen some references to EI 1 through about EI 100.

I don't fear the experimentation but even with home processing @ about 5
minutes a pop it is time consuming and I of course want to spend as much
time in the light as possible.

Anyone with ballparks based in actual pinhole exposures?

Thanks in advance
