Mr Rusty thanks for your response.
I expose full 8x10 sheet as a test strip. I set the aperture at f8 (two stops down from fully open). I expose in increments of 5 seconds. For example: the first segment 5sec, second 5 sec exposure: the first segment now becomes 10sec and the second segment is 5sec, the third 5sec exposure: the first segment now becomes 15sec, the second segment becomes 10sec and the third segment becomes 5sec. and so on. For final print I chose second last segment of 10sec exposure as it looks best in my opinion. I do not change any setup including enlarger hight. Ilford recommends development time of 1 minute. That what I was doing. I do agree that #2 is soft.
