When the `alh-replace:type`

epic`/alh-replace`

is switched to accumulate value, its original value estimates are preserved and can be used to compare with the accumulated value.

#### Value Estimate

The original value estimate is the quantification of how much value is obtained by completing this `alh-epic`

`/alh-replace`

.

alh-optional:enableBValueWorstCase

Value is estimated with both an *expected* and *worst-case* estimate. The *expected* is the realistic estimate of the work needed with 50% certainty (it should not be confused with an optimistic best-case estimate). The *worst-case* estimate with a 90% certainty. The *worst-case* value estimate will always be less than the *expected* estimate.

#### Uncertainty of Value Estimate

Uncertainty is the distance between *expected *and *worst-case* effort in percentage. The higher the difference between the two, the higher the uncertainty. Read more about working with uncertainties.
