How to calculate update progress?

This is the check for whether the node needs to be updated:

storj/common/blob/9815a85cbc32f3fc9c234b35099807119ab5a4e0/version/version.go#L285


      
          	hash := hmac.New(sha256.New, rollout.Seed[:])
          	_, err := hash.Write(nodeID[:])
          	if err != nil {
          		panic(err)
          	}
          	return bytes.Compare(hash.Sum(nil), rollout.Cursor[:]) <= 0
          }
          
          // ShouldUpdateVersion determines if, given a current version and data from the version server, if
          // the current version should be updated. It returns the Version to update to or an empty Version.
          func ShouldUpdateVersion(currentVersion SemVer, nodeID storj.NodeID, requested Process) (updateVersion Version, reason string, err error) {
          	// first, confirm if an update is even necessary
          	suggestedVersion, err := requested.Suggested.SemVer()
          	if err != nil {
          		return Version{}, "", err
          	}
          	if currentVersion.Compare(suggestedVersion) >= 0 {
          		return Version{}, "Version is up to date", nil
          	}
          
          	// next, make sure we're at least running the minimum version. See

Ultimately the cursor magic is checked in

          	return cursor
          }
          
          // ShouldUpdate checks if for the the given rollout state, a user with the given nodeID should update.
          // Deprecated and should eventually be unexported. Please use ShouldUpdateVersion instead.
          func ShouldUpdate(rollout Rollout, nodeID storj.NodeID) bool {
          	return isRolloutCandidate(nodeID, rollout)
          }
          
          func isRolloutCandidate(nodeID storj.NodeID, rollout Rollout) bool {
          	hash := hmac.New(sha256.New, rollout.Seed[:])
          	_, err := hash.Write(nodeID[:])
          	if err != nil {
          		panic(err)
          	}
          	return bytes.Compare(hash.Sum(nil), rollout.Cursor[:]) <= 0
          }
          
          // ShouldUpdateVersion determines if, given a current version and data from the version server, if
          // the current version should be updated. It returns the Version to update to or an empty Version.

I believe the updater checks every 15 min.
