Controlling particle emission quantity

YoshiDude:
Hi, everyone. I'm working on this weapon add-on thing and I'm trying to create an adequate particle emitter for a bullet's explosion. However, it appears to be creating way too many particles. How would I lower it?

Port:
Post the particle and particle emitter datablock.

{
dragCoefficient = 0.2;
gravityCoefficient = 1;
inheritedVelFactor = 1;
constantAcceleration = 0.0;
lifetimeMS = 500;
lifetimeVarianceMS = 55;
textureName = "base/data/particles/chunk";
spinSpeed = 10.0;
spinRandomMin = -500.0;
spinRandomMax = 500.0;
colors[0] = "0.2 0.2 0.2 0.9";
colors[1] = "0.9 0.9 0.9 0.0";
sizes[0] = 0.4;
sizes[1] = 0.5;

useInvAlpha = false;
};
datablock ParticleEmitterData(utaShrapnelEmitter)
{
ejectionPeriodMS = 1;
periodVarianceMS = 0;
ejectionVelocity = 3.0;
velocityVariance = 3.0;
ejectionOffset = 0.0;
thetaMin = 0;
thetaMax = 80;
phiReferenceVel = 0;
phiVariance = 360;
overrideAdvance = false;
particles = "utaShrapnelParticle";

uiName = "";
};
--- End code ---

Port:
Increase ejectionPeriodMS (in utaShrapnelEmitter) or decrease lifetimeMS (in utaShrapnelParticle).

Could you explain what those variables affect?
