Maybe I'm just blind or something, but is there any errata available for Feng Shui?

I was just going through my book and noticed that the juncture modifer to arcanowave is +2 in 1850, surely that isn't right, especially considering the -1 in 69.

Anyone able to set me straight on this?

The closest is the FAQ at Genocide Lounge:

And yes, it should be -2. The first time I read the book I assumed it to be because of some 19th century weird science bonus- which would also be cool.

Thanks. Though I am curious as to why 1850's has a higher penality. Due to both low magic and low tech?

My other theory was that it was meant to be 2 in 69AD and -1 in 1850s.
