Saves Dirk Nowitzki's 1998-99 Topps Chrome #154 to your watchlist, where the daily scan flags listings priced under that card's own comparable sales. That is a different question from this board: the watchlist will not tell you when this ratio moves, and nothing here alerts on the gap.

Why these two
A chrome rookie from the same product line two years later, for a player whose career ranks among the era's best and whose collector base reaches well outside the United States.
What would make this wrong
Two years and two sets apart, and a demand base distributed differently from the anchor's. Same caveat as any cross-set pairing: some of this ratio is the sets, not the players.
How this is measured
Priced on ungraded (raw) copies, not the PSA 9 this pairing names — the price guide returned no value for those grades on this subscription, so both cards fell back to the same basis. The ratio is a like-for-like comparison and the history is sound; the grade in the card names above is what it does not describe.
Each scan records one number: the fair value of Dirk Nowitzki's 1998-99 Topps Chrome #154 divided by the fair value of Kobe Bryant's 1996-97 Topps Chrome #138, both from comparable sales. The baseline is the median of those observations over 90 days — excluding the most recent 21, so a fresh move cannot drag down the very number it is being measured against. Below 8 observations there is no baseline and this page says so instead of showing one.
The baseline is never authored. It is the median of what was recorded, or it does not exist. Nobody types a target ratio into this system.
This is an observation about a historical relationship, not a forecast. A gap that never closes means the market permanently re-rated Dirk Nowitzki rather than temporarily forgot him — that is the risk in every pairing here, and it does not mean-revert on a schedule.
