What the Automatic Hopper Multiplier does
The Automatic Hopper Multiplier is the one knob you have over VICIdial's automatic hopper sizing. Here is what it scales, the range it accepts, and when to move it off 1.
If you let VICIdial size your hopper automatically, the Automatic Hopper Multiplier is the single dial you keep. It does not change the logic of the formula, it just scales the result up or down. Most people leave it at the default and never touch it, but knowing what it does is handy when the automatic sizing feels slightly off and you want a small correction rather than a rewrite.
Where it sits in the formula
When Automatic Hopper Level is on, VICIdial sizes the Hopper from your active agents, your Dial level, and how many call cycles fit in a minute. The multiplier is the last term applied to that calculation. So if the base formula says stage 40 leads and your multiplier is 1.5, the Hopper aims for 60. At 0.5 it aims for 20. The shape of the formula stays the same; only the final size moves.
The accepted range runs from 0.1 to 2.0, and the default is 1, which means the formula runs untouched. Anything under 1 loads fewer leads than normal; anything over 1 loads more. It is a proportional nudge, not a hard override, so the hopper still tracks your live conditions either way. That distinction matters: you are not pinning the hopper to a fixed size, you are telling the automatic sizing to aim a little high or a little low relative to what it would otherwise pick on its own.
When to raise it
Push the multiplier above 1 when the hopper keeps running thin between refills even though your sizing looks right. A busy floor running Predictive dialing with fast cycle times can occasionally outrun the once-a-minute refill, and a multiplier of 1.2 to 1.5 buys extra cushion so agents never wait on an empty hopper.
This is a gentler fix than rewriting your Minimum Hopper Level because it scales with your live conditions instead of pinning a flat number. You keep all the benefits of automatic sizing and just add a bit of headroom.
When to lower it
Drop it below 1 when you want a leaner hopper. Common reasons include tight call-time windows where you do not want a pile of leads staged that may age out of their window before you reach them, or careful campaigns where you would rather over-load fewer leads at a time so you have a tighter view of exactly what is queued. A multiplier of 0.7 keeps the hopper smaller without forcing you to disable automatic sizing entirely, which is a better first move than switching to a fixed level just to shrink things.
One caveat: the multiplier only matters when automatic sizing is enabled, so it pairs directly with the choice in Automatic Hopper Level versus a fixed level. For how the hopper fits the rest of your pacing decisions, the VICIdial dialing strategies guide ties it together. Move the multiplier in small steps and watch a refill cycle or two before changing it again.
If you would rather skip the tuning and start on a box that is already dialed in, see the plans and pricing.
Frequently asked
- From 0.1 up to 2.0. Below 1 loads fewer leads than the base formula; above 1 loads more. The default is 1, which uses the formula as-is.
- No. It only scales the automatic formula. If you are using a fixed Minimum Hopper Level, the multiplier has no effect.
