Exactly! But by doing a 2/2 split you don't add any more 4 CMC cards. And hitting your second Frienzy off of your fist is bad, Chandra would be much better.
It seems like you would be comparing drawing chandra to drawing a cheap burn spell, instead of comparing getting two frienzys vs. one frienzy and one chandra
But you want more 4 CMC cards with Chandra in deck... You want those Phoenixes mainboard. And Frenzy doesn't want it.
Personally I wouldn't even run 4 copies of either Frenzy or Chandra maindeck. Even in RNA people were cutting these for more burn.
But you can easly test this split on Arena and post results here
You don't want more 4 CMC cards with Frenzy around. Frenzy is great because it can provide you huge card advantage by playing multiple cards in a row and by doing so you have to stay on low on curve. Especially when you have Runaway Steam-Kin or 2 on board, you can just go off the turn you cast it.
Chandra is more consistent, allows to easly play maindeck 3-4 drops and is harder to interact with (ppl right now play more enchantment removal). She's better for slower iterations of the deck and in games that card value matters.
From my experience you have to be really explosive with aggro decks right now and Frenzy allows for much more devastating turns compared to Chandra.
You have to realise that both cards take 1 of your turns off and payoff of both cards is either next explosive Frenzy turn or slow, grindy Chandra turns. If you get both Frenzy and Chandra on board as mono Red player you're losing 2 turns for what? Filtering lands
Experimental Frenzy works much better in cheap, burn, The Flame of Keld style Red decks. Chandra, Fire Artisan is stronger in Red decks with higher 3-4 CMC creature count - Whirlers, Phoenixes, etc. All depends on deck build. I don't think mixing up them is a good idea, it's either one or the other.
Personally as a White Weenie player I've yet to lose a game vs RDW with Chandra. Playing her is pretty much dead turn for Red player and in games vs other aggro decks it might be deadly. Still I'd go with her over Frenzy right now until control decks will play more planeswalker removal instead of Mortify.

From my friends experience Tibalt, Rakish Instigator is great sideboard card vs Sultai (stops Wildgrowth Walker and Hydroid Krasis which is a LOT) and less vs Controls. Against everything else he's rather weak.
