No it is not. Depending on which pump cam you are using, the pump shot will last between 50% throttle blade rotation and even up to 80% throttle blade rotation.
If you are cruising, you are only at 20-30% throttle rotation as a guess. The pink cam has the least amount of volume at 30% throttle position. As a reference, the orange pump cam has 30% more volume than the pink cam at the same 30% throttle blade rotation (depending on which pump cam chart you go by). The orange cam has allot more fuel volume and it lasts up to 70% throttle blade rotation.
To test this, with your engine off, just rotate the throttle and watch how far you have to move it until the pink cam quits shooting fuel. The pink cam is a 80% cam but it is in the middle on the volume chart, but it is very lean for most of its duration.
