Increase HP & SP Recovery Tick

[jamesandrew]

How do I change the default regen tick from 10s to 5s?
Am I looking on correct codes?

		// Only players have skill/sitting skill regen for now.
		sregen = regen->sregen;

		val = 0;
		if( (skill=pc_checkskill(sd,SM_RECOVERY)) > 0 )
			val += skill*5 + skill*status->max_hp/500;

		if (sc && sc->count) {
			if (sc->getSCE(SC_INCREASE_MAXHP))
				val += val * sc->getSCE(SC_INCREASE_MAXHP)->val2 / 100;
		}

		sregen->hp = cap_value(val, 0, SHRT_MAX);

		val = 0;
		if( (skill=pc_checkskill(sd,MG_SRECOVERY)) > 0 )
			val += skill*3 + skill*status->max_sp/500;
		if( (skill=pc_checkskill(sd,NJ_NINPOU)) > 0 )
			val += skill*3 + skill*status->max_sp/500;
		if( (skill=pc_checkskill(sd,WM_LESSON)) > 0 )
			val += 3 + 3 * skill;

		if (sc && sc->count) {
			if (sc->getSCE(SC_ANCILLA))
				val += sc->getSCE(SC_ANCILLA)->val2 / 100;
			if (sc->getSCE(SC_INCREASE_MAXSP))
				val += val * sc->getSCE(SC_INCREASE_MAXSP)->val2 / 100;
		}

		sregen->sp = cap_value(val, 0, SHRT_MAX);

		// Skill-related recovery (only when sit)

I tried changing both of these codes but the tick time didn't change.
val += val * sc->getSCE(SC_INCREASE_MAXHP)->val2 / 100;
val += val * sc->getSCE(SC_INCREASE_MAXSP)->val2 / 100;
to 
val += val * sc->getSCE(SC_INCREASE_MAXHP)->val2 / 50;
val += val * sc->getSCE(SC_INCREASE_MAXSP)->val2 / 50;

That's value not a tick.

Try find it on other locations.
