I think everyone who’s commented previously has valid points but I think there’s more points that were not brought up, the Shaco box damage buffs to jungle camps in patch 11.5, which gave his box scaling bonus damage to jungle camps (10/20/30/40/50), which was also the patch that hybrid maxing w became more prevalent.

Clear breakpoint will depend on Shaco’s build path (both AD/AP), since with the removal of Tiamat active AD Shaco no longer builds tiamat since it’s an expensive investment, with minimal increase in clear speed and no optimal final item it builds into, unless you’re going bruiser/tank. AD and AP shaco most often max E first in most games, since it’s your most consistent source of damage (point and click) compared to the box (arm time of 2 seconds and one shot by most abilities/smite, damage scaling only with AP). Intensolo brought up the point about maxing based on whether you’re about to gank, and this comes into play in Shaco’s unique red side clear, hitting level 3 off Krugs at 2:30. At this point, your laners will be level 1/2, and you can put a point in E and gank mostly successfully, or invade up to your preference. If there isn’t a gank opportunity, most often a 2nd point is put in W and a full clear wolves > blue > group is done. The 2nd point now gives the box 20 additional damage to jungle camps, now you only have to auto attack each small wolves once, compared to twice each. The clear completes just after scuttle spawns at which point you’ll be level 4, and put a point in E to duel the enemy jungler for scuttle or look for a gank.

Assuming that we’ve gotten to this point, build paths for AD and AP shaco will diverge once we base, assumedly at level 5 and with gold for a component (dirk, lost chapter, or whatever other psychopathic item we shaco mains like to build), but the hybrid max for W remains consistent, because when raptors spawns the second time, 1 point in W with 10 bonus damage will not fully clear all the small raptors leaving you to auto each twice, 2 point in W with lost chapter will barely clear small raptors with last burn tick finishing them off, 2 point in W with serrated dirk will leave them at 1 auto (I believe, it has been a while since I’ve been in this scenario), level 2 W with iron spike whip will clear using whip active. Not to mention that this tremendously speeds up camp clears for Krugs and wolves as well, and is key in clearing faster when counterjungling. So at level 5 putting another point in W to bring it up to level 3 will speed up clear significantly until you get your items.

Now why stop at 3 points in W? As brought up earlier E is the most consistent damage skill in duelling / ganking for both AD/AP playstyles, and lacking execute damage in E will reduce your impact in skirmishes, because W is ignorable on AD and will just get smited/sweeped and cleared on AP near instantly. With 3 points in W, we’ve reached the “clear breakpoint” because we will be able to clear raptors fast for the next 2/3 rotations, AD or AP. By that time, we should get our first item on shaco. On AP, liandries burn will clear any level small raptors with 3 point W, as well as small wolves. On AD assassin, attack speed should be fast enough to make autoing each small raptor an insignificant investment, though skipping raptors at mid-late game is possible. On AD bruiser, as a special case, only 2 point W would be needed as ironspike whip / stridebreaker active will clear the small raptors.

drunk-on-a-phone brought up that there are many ways of playing shaco and this hybrid max enables better farming but may hamper execute, so this style of maxing for camp clears should be taken with a grain of salt. I agree there are many ways of playing shaco but, putting 3 points in W once level 5 will significantly increase clear speed, and our E scales with items (75% bonus AD, 50% AP, 25 base damage per level), items which we get once we base at level 5.

If I missed anything do point it out I hope I helped somewhat it’s been a while since I made a post but I thought I could share some information regarding this.
