The deuce already fills one slot of the run, so a single card finishes a straight flush: the 4♣ and 5♣ (making 4-5-6-7-8 with the deuce as the other), the 9♣ and 10♣, and any of the three remaining deuces — seven of the 47 unseen cards, each worth 9 coins. Every other club gives the flush back for 2; an off-suit 4, 5, 9 or 10 makes a straight for 2; an off-suit 6, 7 or 8 pairs with the deuce for three of a kind. Add it up and the one-card draw is worth 2.2128 against a flat 2.0000 for standing pat. The connectors matter: the chart's line runs from 5-6-7 to 9-10-J because those are the suited three-card runs with four natural ranks completing them. Below that the 2 under the run is a wild card, not a card you can draw (4-5-6 has three natural outs), and 10-J-Q suited with a deuce is a wild-royal draw, a line higher. The same hand without the Q♣ — a deuce with 6-7-8 suited and a blank — is the same chart line; the pat flush is just what makes players hesitate.
Chart line #14 of 33 — 'A deuce + 3 suited consecutive cards 5-6-7 up to 9-10-J — draw one (even from a pat flush or straight)' — sits above line #15, the made three of a kind, straight or flush with a deuce.
