There are a LOT of bullshit claims by kite companies regarding light wind capabilities. NO kite will perform in < 7-8 knots. The owners and distributors of the Epic Infinity are among the worst offenders. To claim the Epic Infinity can perform in "2-4 knots" (even if it is with a SUP) is ridiculous and a blatant lie and leaves the company wide open to claims from disgruntled users.
WIND GRADIENT & FETCH
The use of anecdotal evidence to try to support a generalisation is always suspicious. Epic's owners continually posting videos & images of kites flying in conditions without whitecaps and claiming "5 knots" are misleading; obviously wind gradient http://en.wikipedia.org/wiki/Wind_gradient
and/or short wind "fetch" http://en.wikipedia.org/wiki/Fetch_(geography
) are involved.
RELATIVE KITE PERFORMANCE
The ONLY way to gauge the RELATIVE performance of kites in light winds is to fly them side-by-side, with similarly experienced riders and similar boards.
LIGHT WIND KITE DESIGN
It is simply not possible for the Epic Infinity (V1, 2, or 3) to surpass significantly the performance of every other light wind kite in existence. There is NOT enough energy for ANY kite to perform in "2-4 knots of wind". With BIG light wind kites, various modifications have been tested over many years: Fast-turning big kites need to be fat (i.e. lower aspect ration & long middle struts), but the payoff is poorer upwind ability and slightly inferior low-end. Narrower (high aspect ratio) kites go upwind better, but turn more slowly. e.g. Flysurfer's "Speeds" are very narrow, but very SLOW turning. There is no such thing as a fast-turning, ultra-low end, exceptional upwind, easily relaunchable kite with a lot of range; there's always a trade-off.
Epic's Bad Sportsmanship & Fundamental Dishonesty
Recently, EPIC's ~16m V3 Infinity challenged a 19m kite to a "duel". Epic lost. During the duel, despite having plenty of opportunity to use line extensions and a surfboard, Epic refused to do so, "because (he) didn't need them". But to subsequently use this as an excuse for losing is …. pathetic and fundamentally dishonest. This fundamental dishonesty was compounded by outright slander, claiming the opponent had to swim out to get started.
Epic Lies & Exaggerations
Epic's owners are well known to stretch the truth, e.g.:

Infinity V2 has the power of a 19 meter but turns like a 14 meter.
Compared to the Core19m kite, the Epic Infinity V3 was noticeably INFERIOR; it certainly didn't have the "power of a 19m".
Until this vid surfaced, Epic was claiming light wind domination at this event. The inferiority of the Epic Infinity in light winds is demonstrated, as is the fundamental dishonesty of Epic in trying to portray otherwise. Epic struggling and then collapsing into the water while the Cabrinha LW kite blasts past. Compelling. Hilarious! And a savage indictment of Epic and its marketing. The Epic Infinity can NOT fly in ?7/8 knots, let alone 2-4 knots.
SUP-kiting in 9 Knots
Despite the "2-4" knot claims, the Epic Infinity CANNOT perform on a SUP until ~ 9 knots.
STOP THE BULLSHIT: RETURN THEIR KITES
There IS a simple way to put to rest ridiculous claims by Epic or any other kite company: BUY THEIR KITES. If they don't perform in 2-4 knots on a SUP or whatever - let alone below 7-8 knots (and they won't), then return them. A "class action" against these companies, perhaps using this forum as a meeting point, will force these companies to be more truthful.
Ignore the lies. Ignore the propaganda.
No kite can perform under 7-8 knots, let alone 2-4 knots.
