Merigold and Jan,
Bless you a thousand times for replying!
In typing out the 4 RS rnds so that you could help me figure out what the blazes I've been doing wrong, it hit me at long last:
The k3-into-3 instruction throughout the previous 3 RS rnds suddenly changes to k3-into-1
in rnd 7. DUH! I truly had not noticed, so accustomed was I by that time to the k3-into-3.
Eureka! I feel like shouting it from the rooftops!
Genuflections--I love this site and this forum, whose helpful videos have taught me so many new techniques.
