[Vocabulary] Alternative to "must have"

[GentleBoy]

Hi Teacher,

Please tell me if there is any alternative to "must have". In my understanding "must have" is only used for expressing expectation in past.
If the thing expected was less certain can I use "would have" instead.

Example- You must have practiced music regularly as a child. (Meaning- 'You' are expected to have practiced... )

Can the following sentence mean the same thing with less certainty.

You would have practiced music regularly as a child.

If it is not correct use, should we use "must have" even for the context with less certainty.

Thanks,
GentleBoy

There are some possible alternatives, but I like you must have`` best. To me it is the most idiomatic and natural. Examples:

Beyond doubt you practiced music regularly as a child.

It seems certain that you ...

The only explanation for your prowess is that you ...

This can mean two things. 1) As a stipulation, for example as a requirement for entry to a prestigious music school. (Similar to your explanation, I think). 2) "You are so good, I assume that you practised regularly as a child".
Other examples of the same:
1) "You must have passed XY101 if you want to take XY201." - It is necessary for you to have passed.
2) "You must have passed XY101. You seem to know a lot!" - It is likely that you have passed.

I am sorry. I think my question got lost somewhere in the discussion.
Let me put it in a clear way.

I am considering the context as "some regular activity which is expected to have been done in the past" .
What I am wondering is when we use "must have" it represents certainty (if my understanding is correct).

If "certainty" is NOT our concern how should I form the following sentence.

You _________ have gone there many times.

Please consider my context and tell me how should I fill up this. What are the possible answers ?

It is almost impossible to put accurate degree of certainty on these constructions, because individual speakers use them in different ways.As some speakers do not use the whole range, the ones they do use cannot have exactly the same meaning as when those are used by somebody who does use the whole range.

My own personal view is:

He did/didn't do it. Fact.
He will have done / won't have done it. Certainty.
He must/can't have done it. Logical certainty.
He may / may not have done it. Possibility
He might /might not have done it. Lesser Possibility.
He could have done it = Similar to 'might have' or Potential ability at the time to do it

would / wouldn't have done it is, for me, less certain than 'will/won't' and more certain than 'may / may not'.

He couldn't have done it expresses, for me, a greater possibility of the past non-doing than 'may not'.
