For easy reference, Update 11.3 had this to say about Sentinel exp mechanics:

Based on reports and experiences with slow-ranking Sentinels, we have changed the way Experience is distributed amongst your feisty friends.
 * Previously: Sentinel kills would split experience between your Sentinel’s weapon and your Warframe, so your Sentinel itself would miss out on experience. Weapon kills would split evenly between your Warframe and your Weapon (50% each), then a 42% bonus chunk of experience would be given to the Sentinel and its weapon (21% each). Note that the total XP earned was 142% of what you saw on the screen – now it will be 200%.
 * Now: Regular weapon kills divide experience evenly between your weapon and your Warframe (50% each). Kills using a Warframe ability give all the experience to the Warframe (as before). Sentinel weapon kills divide experience evenly between your Sentinel and its weapon (50% each). Kills using a precept give all the experience to your Sentinel (as before). Experience from other players (shared experience) is split evenly amongst your gear as follows: a quarter goes to your Warframe and a quarter goes to each of your weapons (25% each). If you have a sentinel equipped, a 100% bonus chunk of experience is split evenly between your Sentinel and its weapon (50% each).
