The bar a win has to clear

Most feeds have a stated bar and no reader ever sees it. Where it is stated it is usually written in multiples - "250x" - which is a number about the game rather than about the money, and it hides the stake the way a percentage hides the amount.

Stated bar: 250x the stake
Same win at 0.20: 50.00
Same win at 5.00: 1,250.00
Clearing the bar: still 1 in 38 shown

the barThe multiple a win must reach to be eligible for the display - on the sample, 250 times the stake

the poolThe players and spins the rows were drawn from - on the sample, 4,750 players placing 1,900,000 spins in the hour

the intervalThe hours between one player's own qualifying wins - on the sample, 10.4 hours at 400 spins an hour

Direct answerA feed’s threshold is the multiple a win must reach to be eligible, commonly 100x to 500x the stake. It is a real filter and it is not the reason a reader is not in the feed: on the sample, 457 wins cleared the 250-times bar in one hour and the feed showed 12 of them, so clearing the bar buys a 1 in 38 chance of a row.

The same bar, in money

A bar written in multiples says nothing until it is multiplied by the stake, and the stake is the one field a lot of feeds omit. The same 250-times win is a modest amount to one player and a large one to another, and the bar cannot tell them apart.

One bar, four stakesthe bar                       250x
stake 0.20   ->  the row reads    50.00
stake 1.00   ->  the row reads   250.00
stake 5.00   ->  the row reads 1,250.00
stake 20.00  ->  the row reads 5,000.00
stake omitted -> the reader cannot tell which of the four
                 they are looking at

Nine of twelve. Across the sample book, 9 of the 12 sites that run a feed show only the multiple and not the stake. The bar is stated in the unit that hides the money, which is the opposite of what a reader trying to judge a row needs.

Clearing the bar is necessary, not sufficient

A threshold filters eligibility, not visibility. On the sample the 457 qualifying wins in the hour competed for 12 rows, so the bar is the first of two filters and the second one - the selection - is the one that shapes the feed.

Two filters, and which one moves the readerspins in the hour                        1,900,000
1 in 4,155 clears the 250x bar   ->        457 wins
rows shown                                    12
chance a qualifying win is shown   12 / 457 = 2.6%
for one player at 400 spins/hour   400 / 4,155 = 9.6% an hour

Raising the bar would make each row larger and would shrink the pool behind it; the sample bar is set where a real, if uncommon, player win lands, so that the rows are both plausible and numerous. Lowering it to 25-times, which is the celebration bar on S5, admits so many wins that the display would fill in seconds.

How to use a bar

Find the bar before reading any row. If no threshold is published, treat the feed as an unfiltered sample of nothing in particular, because that is what an unstated rule amounts to.
Convert the bar into money at your own stake. A 250-times bar is a different display to a player staking 0.20 than to a player staking 20.00.
Ask how many wins cleared it. The bar alone does not say whether the feed is showing all of them or one in thirty-eight.
Notice whether the rows carry a stake at all. A feed of multiples with no stakes cannot be turned into money, which is the field a reader most wants.
Remember what the bar is not: it is not a target, not a forecast, and not a promise that the same game will produce the same multiple for you.
