In the example you give, the opponent’s Shoryu, if timed correctly, will beat yours. That’s because they will recover slightly quicker than you. Your shoryu will beat their counter throw attempt, however.
What you want to do is vary ticks. If you always do cr. lk tick, throw, then mix it up with cr lk X 2 , throw, or finish the entire block string, like cr lk X 3, cr mk X Hadoken, etc.
One thing to also be aware of is that Ken’s MP throw has more range. Sometimes you can do like cr lk x 2 and be out of knee bash range, but still in range for that throw.
