We use a review queue to manage reviews. If your PR does not appear there, it is probably because it is not successfully building (i.e., it doesn't have a green checkmark), has the awaiting-author tag, or another reason described in the Lifecycle of a PR. The review dashboard has a dedicated webpage which shows whether your PR is on the review queue, and (if not), why.

If you haven't already done so, please come to https://leanprover.zulipchat.com/, introduce yourself, and mention your new PR.

Thank you again for joining our community.

• The relative value is the weighted sum of the differences with weight given by the inverse of the current value of the statistic.
• The absolute value is the relative value divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).

Suggested change

	theorem type_uLift : type (ULift.{v, u} α) = lift.{v} (type α) := by
	rfl
	theorem type_uLift : type (ULift.{v, u} α) = lift.{v} (type α) := rfl

[YanYablonovskiy]

It is bizarre, the term Eq.refl (type (ULift.{v, u} α)) is accepted, however rfl fails with

  type (ULift.{v, u} α)
is not definitionally equal to the right-hand side
  lift.{v, u} (type α)

Note: This theorem is exported from the current module. This requires that all definitions that need to be unfolded to prove this theorem must be exposed.```

[YaelDillies]

Is this because you are missing @[expose] on one of the relevant definitions?

[YanYablonovskiy]

Perhaps it is because type is @[no_expose]
