"At the latitude of Slaggyford there are two areas , to the north and south ,both extending to approx 66 degrees of the horizon where the sun and moon never sets or rises . The remainder of the horizon ,228 degrees (360 minus 132 degrees ) is where the Thom paradigm events and directions can be measured "

Have a look at diagram 8.1 in Thom's Megalithic Sites In Britain. It's titled Histogram of observed declinations. He measured sites with alignment declinations from -30, the moon at standstill, to +40, which he hypothesised was to fixed stars. That makes a lot more of the horizon available than you suggest. ..
